相对论J矩阵方法

Relativistic J-matrix method

Pawel Horodecki

摘要:

本文给出了相对论形式的J矩阵法求解势消失快于库仑势消失的散射问题。在非相对论的情况下,它导致一个有限的代数本征值问题。推导出的相移正切表达式与非相对论情况下的公式简单相关,并给出了后者的极限情况。这是由于所使用的基组满足“动力学平衡条件”。

英文摘要:

The relativistic version of the J-matrix method for a scattering problem on the potential vanishing faster than the Coulomb one is formulated. As in the non-relativistic case it leads to a finite algebraic eigenvalue problem. The derived expression for the tangent of phase shift is simply related to the non-relativistic case formula and gives the latter as a limit case. It is due to the fact that the used basis set satisfies the ``kinetic balance condition''.
