摘要
一种两维积分（从离子─原子碰撞中的两中心矩阵元分离得到）通过引入Ｌａｐｌａｃｅ变换而解析地积出，并用变形的Ｂｅｓｓｅｌ函数来表示。传统的Ｆｅｙｎｍａｎ变换对于这种与激发态俘获相关的更一般的积分是非常复杂的。
A kind of two-dimensional intesrals,separated from two-center matrix elements in ion -atom collisions, is analytically integrated by introducing the Laplace transform into the integrals and expressed by the modified Bessel functions. The traditional Feynman transform is very complicated for this kind of more general integrals related to the excited state capture.
