摘要

在现实中，电磁相互作用会在一定距离内被屏蔽，因此，我们考虑了屏蔽或截止库仑势，以直观地反映现实情况下的屏蔽效应。通过微分方程方法，我们构建了在 Hulthén 修正的秩一可分离势中运动的壳外解和过渡矩阵的精确解析表达式。上述势的壳外过渡矩阵尚未在文献中讨论过。通过一些模型计算检验了这些表达式的实用性。

Analytic T-matrix for the Hulthén-distorted Yamaguchi Potential-application to $$\alpha -12C$$ Scattering

The electromagnetic interaction, in reality, is screened at a distance, and thus, the screened or cut-off Coulomb potentials are considered to visualize the effect of screening in real situations. The exact analytical expressions for off-shell solutions and transition matrix are constructed for motion in Hulthén-modified rank-one separable potential via the differential equation approach to the problem. The off-shell transition matrix for the said potential has not yet been discussed in the literature. The usefulness of these expressions is examined through some model calculations.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
