charge independence

charge independence

[¦chärj in·də′pen·dəns]
(nuclear physics)
The principle that the nuclear (strong) force between a neutron and a proton is identical to the force between two protons or two neutrons in the same orbital and spin state.
(particle physics)
As a generalization of the nuclear physics definition, the principle that the strong interactions of particles are unchanged if a particle is replaced by another particle of the same isotopic spin multiplet.
