耦合到1/r奇异矢量势的全角动量Dirac方程

Dirac equation with coupling to 1/r singular vector potentials for all angular momenta

A. D. Alhaidari

摘要:

本文考虑3+1维球对称Dirac方程,方程与1/r奇异矢势耦合.得到了所有角动量的近似解析解。这种近似是针对狄拉克方程本身中的1/r轨道项,而不是针对所得二阶微分方程中传统且更奇异的1/r^2项。因此,该解决方案的有效性是一个更广泛的能量谱。作为例子,我们考虑的Hulthen和Eckart潜力。

英文摘要:

We consider the Dirac equation in 3+1 dimensions with spherical symmetry and coupling to 1/r singular vector potential. An approximate analytic solution for all angular momenta is obtained. The approximation is made for the 1/r orbital term in the Dirac equation itself not for the traditional and more singular 1/r^2 term in the resulting second order differential equation. Consequently, the validity of the solution is for a wider energy spectrum. As examples, we consider the Hulthen and Eckart potentials.
