作为总自旋函数的最高和最低能量是针对自旋 1/2 原子线性链的 Bethe 形式中的“未束缚”态类计算的，在最近邻居之间具有海森堡交换相互作用。最低能量用于计算无限反铁磁链在零温度极限下的磁化曲线。在零温度和零磁场下，磁化率值为 0.050661 g 2 μ 2 J，其中 μ 是玻尔磁子，g 是电子 g 因子，相邻自旋之间的相互作用的形式为 2 J S 1· S 2。
The highest and lowest energies as a function of the total spin are computed for the class of" unbound" states in the Bethe formalism for the linear chain of spin-½ atoms with a Heisenberg exchange interaction between nearest neighbors. The lowest energies are used to compute the magnetization curve for the infinite antiferromagnetic chain in the limit of zero temperature. At zero temperature and in zero field, the magnetic susceptibility has the value 0.050661 g 2 μ 2 J, where μ is the Bohr magneton, g the electron g factor, and the interaction between neighboring spins is of the form 2 J S 1· S 2.
