This dissertation concentrates on photoionizaiton of mnl and mnll including resonance structure in the framework of many - body perturbation theory ( mbpt ) . more accurate results were obtained by using the new approach to calculate resonance structure and photoionization cross section 首先针对锰原子或离子不同壳层的光电离结构进行特定的理论分析，然后通过合理的选择势能及共振结构的计算方法，并考虑高阶关联，得到了一系列新的更为精确的光电离截面及共振结构。
