WebIn particle and nuclear physics, isospin, I or I3, is a quantum number related to the strong nuclear force. Isospin is associated with a conservation law that requires strong interaction decays to conserve isospin. This term was derived from isotopic spin, but physicists prefer the term isobaric spin, which is more precise in meaning. Webthe two spin states of some abstract “spin”-1/2 object (isospin). Therefore the (internal) symmetry group is the same as that of the ordinary spin, SU(2). More explicitly, the proton and neutron form an isospin double, N= p n!, (3.2) which transforms under isospin rotations as, N′ = UN, (3.3) where U is a 2 × 2 (uni-modular) unitary matrix.
