评“具有自旋和赝自旋对称性的Woods-Saxon势的Dirac方程的解”[J.Y. Guo和Z-Q。Sheng,Phys. Lett. A 338(2005)90]
Comment on `Solution of the Dirac equation for the Woods-Saxon potential with spin and pseudospin symmetry' [J. Y. Guo and Z-Q. Sheng, Phys. Lett. A 338 (2005) 90]
摘要:
在上述四种束缚态解中。引用,只有一个(即,自旋对称的,在低质量的制度)是兼容的物理边界条件。我们澄清问题,纠正方法,并提供另一个,“失踪”(即,伪自旋对称)的新的解决方案与某些违反直觉的“排斥产生”的性质。
英文摘要:
Out of the four bound-state solutions presented in loc. cit., only one (viz., the spin-symmetric one, in the low-mass regime) is shown compatible with the physical boundary conditions. We clarify the problem, correct the method and offer another, "missing" (viz., pseudospin-symmetric) new solution with certain counterintuitive "repulsion-generated" property.
