I find that this field gets very little attention but is very interesting.
By this I mean theory of nuclear structure and nuclear reactions, in lower energies, such that elementary particle physics is not considered but we can pretend that "there is nothing underneath protons and neutrons".
I am starting a PhD soon in this field, and it is very specific and has many interesting phenomena which I find are not that known. For example, did you know that superfluidity occurs in nuclei to produce energy gaps in energy levels of the nucleus? And that taking this effect into account results in better prediction of the outcomes of nuclear reactions?
So, if you are doing anything related to nuclear structure/nuclear reactions, please leave a comment. #science
