query: What can we learn with nuclear physics?
passage: Nuclear physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. Other forms of nuclear matter are also studied.[1] Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons.
passage: Nuclear force
In recent years, experimenters have concentrated on the subtleties of the nuclear force, such as its charge dependence, the precise value of the π"NN" coupling constant, improved phase shift analysis, high-precision "NN" data, high-precision "NN" potentials, "NN" scattering at intermediate and high energies, and attempts to derive the nuclear force from QCD.
