求解了Mie型势的Dirac方程。利用赝自旋和自旋对称性研究了能谱和相应的波函数。利用Nikiforov-Uvarov方法得到了Dirac方程的解析解，并得到了任意自旋轨道耦合项kappa的能量本征值的封闭形式.我们还给出了著名的Kratzer-Fues势和修正的Kratzer势（Mie型势）下Dirac粒子的一些数值结果。
Dirac equation is solved for Mie-type potential. The energy spectra and the corresponding wave functions are investigated with pseudospin and spin symmetry. The Nikiforov-Uvarov method is used to obtain an analytical solution of the Dirac equation and closed forms of energy eigenvalues are obtained for any spin-orbit coupling term kappa. We also present some numerical results of Dirac particles for the well-known Kratzer-Fues and modified Kratzer potentials which are Mie-type potential.
