同位旋形式在核物理中的应用源于强相互作用几乎不依赖于电荷的假设。除了近似地认为中子和质子具有相同的质量外，同位旋形式还将中子和质子描述为具有同位旋T=1/2的相同粒子，投影分别为Tz(N)=+1/2和Tz(P)=−1/2[1，2]。具有相同同位旋T的同压核属于2T+1多重态，投影Tz=(N−Z)/2，其中N是原子核中的中子数，Z是原子核中的质子数。相应的-
The application of the isospin formalism in nuclear physics stems from the assumption that the strong interaction is almost charge-independent. In addition to the approximation that the neutron and the proton have the same mass, the isospin formalism describes the neutron and the proton as identical particles with isospin T = 1/2 with the projections Tz(n) = +1/2 and Tz(p) = −1/2, respectively [1, 2]. Isobaric nuclei with the same isospin T belong to a 2T +1 multiplet with the projections Tz = (N −Z)/2, where N is the number of neutrons and Z the number of protons in the nucleus. The correspond—
