Total angular momentum is a physical quantity that describes the overall rotational motion of an object, taking into account both its spin and orbital angular momentum.
Nucleons are the particles that make up the nucleus of an atom. They include protons and neutrons.
The total angular momentum of two nucleons is calculated by adding their individual angular momenta together. This includes their individual spin and orbital angular momenta.
The possible values for the total angular momentum of two nucleons are whole numbers ranging from 0 to the sum of the individual angular momenta of the two nucleons. For example, if one nucleon has a spin of 1/2 and the other has a spin of 1, the possible values for the total angular momentum would be 0, 1, and 2.
The total angular momentum of two nucleons does not directly affect the stability of an atom. However, it does play a role in determining the energy levels and possible transitions of electrons in the atom, which can ultimately affect the stability of the atom.
