WebProblem 17 Easy Difficulty. Isospin, or isotopic spin, is a quantum variable describing the relationship between protons and neutrons in nuclear and particle physics.
WebIsospin symmetry is an important symmetry in particle physics, although it occurs only in the action of the nuclear binding force--or, in modern terminology, the strong nuclear force. The symmetry leads to the conservation of isospin in nuclear interactions that occur via the strong force, thereby determining which reactions can occur.
