摘要:

利用$SU(1, 1)$李代数的径向部分,得到了Dirac氢原子的束缚本征函数和谱.为了定义代数,我们需要在描述中添加一个额外的角度变量,它基本上扮演相位的角色。用代数上的算符定义相对论性氢原子径向本征函数的梯形算符,并计算其能谱。研究了Johnson-Lippman算子在该代数中的地位。

英文摘要:

The bound eigenfunctions and spectrum of a Dirac hydrogen atom are found taking advantage of the $SU(1, 1)$ Lie algebra in which the radial part of the problem can be expressed. For defining the algebra we need to add to the description an additional angular variable playing essentially the role of a phase. The operators spanning the algebra are used for defining ladder operators for the radial eigenfunctions of the relativistic hydrogen atom and for evaluating its energy spectrum. The status of the Johnson-Lippman operator in this algebra is also investigated.
