复势散射

摘要

在量子物理学中，散射问题是十分重要的，在其它领域中（如天体物理学、化学、粒子物理、激光物理等）也有着非常重要的作用。然而，在一般教科书中只讨论了粒子被实势散射的情况。本文采用分波法研究了粒子被中心复势场散射的问题，求得了总散射截面。%Scattering problem are of fundamental importance in quantum physics and and play also an important role in other fields such as astrophysics , chemistry , plasma physics and laser physics and so on .However ,the scattering of a paricle by a real potential in most textbooks are considered .In this paper , we have dicussed in some detail the typical problem of the quantum theory of scattering by a central complex potential using the method of partial waves , and we obtained the total cross-section .
