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。该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.
