Hey, is there software out there capable of simulating heavy nuclei? For instance, U235 or other fissile materials? When I say simulating, I mean using all the appropriate equations (nuclear strong force fields represented, Schrodinger equations represented, etc). Mainly, I would want one that can simulate the nuclei being bombarded by photons. Also, what's a good place to start in terms of reading material when it comes to understanding the behavior of nuclei? I have a basic textbook on nuclear physics, but I'm wondering mainly about the specific topic of the reaction of the nuclei to different wavelengths of light. I know photo-fission is a topic I've skimmed a paper on or two, but I'm wondering if there's ways of characterizing nuclei or modeling/simulating them using computers. I'm guessing if there is some kind of freeware available, it's not something I could just run on my laptop, but that's why I'm asking. I'm also asking because it's a little outside of my academic experience (though not outside of my basic understanding). Anyway, let me know what's a good direction to start (preferably using resources on the internet if possible).
