The simple single-channel static-exchange approximation completely ignores correlation between the continuum and molecular ion electrons. We present cross sections and molecular frame photoelectron angular distributions with both A grid-based variational method described here makes such single-channel calculations possible on larger systems without local-exchange approximations. \rrl{Illustrative calculations on the core ionization of SF${}_6$ are presented to illustrate the power of the grid-based method.

静态交换近似对多原子分子内壳光电离的有效性

简单的单通道静态交换近似完全忽略了连续谱和分子离子电子之间的相关性。我们用两种方法都给出了横截面和分子框架的光电子角分布。这里描述的基于网格的变分方法使这种单通道计算在没有局部交换近似的较大系统上成为可能。\ rrl {SF核心电离的图解计算${}_6$ 提出来说明基于网格的方法的功能。
