Basic properties of atomic nuclei
... When the total number of nucleons A is even, j is an integer; when it is odd, j is a half-integer. All nuclides for which both Z and N are even have 1 = 0, which suggests that pairing of particles with opposite spin components may be an important consideration in nuclear structure. nuclear magneton ...
