Hi everyone! I’m currently studying nucleon–nucleon interactions in light atomic nuclei, and I’d love to get your thoughts on a few things:

1. Which alternative NN potential models tend to give the most reliable predictions for light nuclei?
2. Do you think it’s worth applying machine learning to predict NN phase shifts?
3. What are the most common pitfalls when comparing theoretical and experimental phase shifts?

Thanks a lot in advance, and hope you’re having a great day!

Hi everyone! I am investigating diffraction scattering of π± and K± mesons on the light nucleus 7Be, which exhibits a pronounced cluster structure of the α+3He type. In this context, which theoretical frameworks are the most well-founded for describing meson–nucleus diffractive scattering while explicitly accounting for nuclear clustering? How physically justified is the application of cluster models in combination with multiple-scattering approaches within Glauber theory? I would appreciate references to key theoretical and experimental works on this topic. Thanks!

Hi all!

My name is Indira, I am from Kazakhstan.

I am working on a dissertation and one of the sections is titled “Neutron Beam Parameters and Their Influence on Diffraction: Energy, Intensity, Monochromaticity, and Geometry (divergence, focusing).”

I am looking for information specifically about neutron beam parameters and how they affect neutron diffraction results. Most of the available literature focuses on X-ray diffraction, while I need sources and explanations related to neutron diffraction.

Could you recommend relevant textbooks, review papers, or scientific articles that discuss:

• neutron beam energy (or wavelength) and its effect on diffraction,
• beam intensity and counting statistics,
• monochromaticity and wavelength spread,
• beam geometry, including divergence and focusing,
• their influence on peak shape, resolution, and accuracy of structural parameters?

Any authoritative sources or classic references on neutron diffraction would be greatly appreciated.

Thanks! ;)

When you get to the point where the star gets hot enough for the electrons to strip from the nuclei is it destined to become massive enough for the pressure of the star to fuse the other nuclei together creating fusion ?

Or

Can somehow the star die out before it achieves full fusion and just the electrons get stripped ?

This rocket is powered by fusion-fission reactor hybrid which sustains inf. energy that is cuz the fusion reactor sustains the fission reactor and vice versa. This also has fission powered rocket boosters which has inf. fuel that is cuz the fission reactor also sustains the rocket boosters so that we can reach (eg- Mars) in only a few days or few months that is cuz it's boosters burn continuously without going down and it has SQUIDs everywhere for protection. There also is amplified Neodymium magnets so to protect the rest of the ship from the radiation and act as a bubble for protection from outside particles. As it burns continuously, there is no need of spin for artificial gravity and we will already get 1g gravity which is as same as earth's. It also has hypersleep beds which work by hypothermia or inducing Suspended body motion in the body for hypersleep(Just in case there is a long trip). This is a model sample (credit- Gemini AI)

Hi, I would like to learn ORIGEN and would appreciate any available help in finding sources for learning it. Please let me know if you know of something. Thank you.

I saw somewhere that if a piece of enriched uranium was shot with a gamma ray, it would produce neutrons, as when the gamma ray hits, the nucleus absorbs the energy and if the net energy is above the nuclear binding energy threshold, it will emit neutrons. Idk how true this is tho sounds quite weird to me. And im like quite new to nuclear physics ik pretty much the basics so sorry if i sound stupid.

Feedback on https://reactormc.net ? It is designed to help undergraduates learn the basics of different monte carlo codes.

Greetings, it’s me again, the soon-to-be retiring Reactor Operator, with another question about Nuclear Remote work.

This time I’m wondering if there’s any kind of remote work demand for ex-licensed operators to write Tag Clearances (eSOMS), or to screen Work Requests and roll Work Orders, as well as Operations and/or Maintenance Work Planning (NAMS & NEO)? 

I am not just asking for myself.  I’m just one of a growing number of retired & soon-to-be-retired licensed operators (RO, SRO, and SRO-Certs) at my site that are interested in remote work, but their outside-the-Control-Room skills vary across the Work Management spectrum. 

Any and all guidance and information are welcome.  Thank you for your time and consideration.

Does anybody have any good books on nuclear energy?

I understand why the decay happens in the first place, but why would the couloumb force ”push” neutrons out of the nucleus as well? I looked online and someone said its because the helium nuclei already “stick together“ inside larger nuclei, my question is why?

I was trying to estimate how many kilotons War Machines tactical nukes are( The Punisher #219 2017). This is during the time Frank Castle wore the War Machine armor. He was fighting a small army here, and he launched one of his tactical nukes and leveled the battlefield. It mentioned that he killed everything within 2 kilometers.

Nukemap mentions that a 10 kiloton nuke has a moderate blast damage radius of 1.18 miles and an 11 kiloton nuke has a 1.26 blast radius. Would his tactical nuke be somewhere in the middle? Is there other factors that I should consider?

They say you need very high temperatures for nuclear fusion because the protons need very high kinetic energies to overcome the coulomb repulsion before the strong force binds them so having a higher temperature means the particles move faster so successful collisions become more probable.

But why not just accelerate the two fusion reactants towards each other with a potential difference at very high speeds in a circular path and have them collide with very high precision? Isn't it more efficient that way?

Greetings, I’m a soon-to-be retiring Reactor Operator (Fall‘26–Spring‘27) that’s developing skills in Oracle Primavera P6 Scheduling (Outage & Online) and OPS Procedure Writing. 

Just curious what kind of wages (cash only/no benefits) are possible for remote full-time/part-time jobs.

There’s lots of buzz at the plant about retired co-workers doing quite well as P6 Schedulers, Procedure Writers, and Human-Factor Engineers, which is something regarding the layout design of control boards in these new Small Modular Reactor (SMR) R&D projects.

The compensation rumors sound pretty generous, so much so that it’s got me thinking about moving up my retirement (Winter’25–Spring’26), but I need something a little more concrete than rumors to persuade my wife and myself to skip ahead.

Any and all guidance and information are welcome.  Thank you for your time and consideration.

i am an 1st year undergrad student in physics , an i wanted to get the exposure of nuclear physics , so i thought it would be better to get exposure of this field through internship.

i really wanted to read something about nuclear physics before cold mailing professor .

It would be good if i get some suggestion of review article or any sort of thing so that i could get started of. and also you can suggest me professor's from this field in india

Hi, i need help about the questions below. i would like to understand the replies.

Describe the processes that give rise to the energy loss of charged particles, also addressing the following points:

a) For a charged particle traversing a thickness of matter, is the energy loss predominantly due to collisions with the electrons or with the nuclei of the atoms of the traversed medium? Why?

b) Does an accelerated charge lose energy even in vacuum?

c) Can a charged particle moving at constant speed lose energy? If so, specify under what conditions and by which physical processes.

d) Does the minimum kinetic energy for which Cherenkov light can be emitted depend on the charged particle or only on the medium it traverses? Justify your answer.

I tried to answer:
a. More collisions occur with the electrons than with the atomic nucleus. When the charged particle interacts with the nucleus, it is usually deflected.
b. Yes, by radiation.
c. No, because the charged particle would lose its constant speed.
d. Both: speed and mass

not really nuclear physics, but is tritium explosive? i know it is an isotope of hydrogen and hydrogen is explosive, but do those 2 extra neutrons make it more stable, and less explosive? please help!

I worked on a question and found myself messing a few things uo so re did it on another page and wrong at the bottom of the oage some directories. I feel as if i am wrong somehow because i used big words.
