对于任意自旋-轨道量子数κ，在自旋对称Δ(r)=C=const和伪自旋对称Σ(r)=C=const的情况下，应用自旋-轨道耦合势的近似，给出了Hulthen势的Dirac方程解析解。以封闭形式得到了束缚态能量特征值和相应的旋量。
For any spin-orbit quantum number κ, the analytical solutions of the Dirac equation are presented for the Hulthen potential by applying an approximation to spin-orbit coupling potential for the case of spin symmetry, Δ(r)=C=const, and pseudospin symmetry Σ(r)=C=const. The bound state energy eigenvalues and the corresponding spinors are obtained in the closed forms.
