Nothing prevents you from working on problems in theoretical physics at home, with whatever degrees you may happen to have. If you want to be a professor of physics at a university, then you would be expected to have a PhD.
And I believe this belongs in "nuclear physics," and I should know, I'm nuclear.

Nuclear physics? Why not just say "physics" for this one? Anyway, that's what they're testing!
Only for researches in nuclear physics/nuclear chemistry.
Nuclear is any activity related to the nuclei of atoms as nuclear energy, nuclear fission, nuclear engineering, nuclear physics, etc.
The study of the structure of atomic nuclei is called nuclear physics. This field focuses on the properties and behavior of atomic nuclei, including their composition, size, stability, and interactions with other particles. Nuclear physics plays a crucial role in understanding processes such as nuclear reactions and nuclear energy generation.
