Endofullerene photoionization of open-shell N@C₆₀ is investigated using a coupled-channel, correlated R-matrix approach with additional modifications for a finite spherical-shell fullerene potential. Particular focus is on the initial-state dependence of the photoionization cross section. Comparisons show significant differences between the 1s ²2s ²2p ³(⁴S) initial state and the metastable ²D and ²P states, as well as strong confinement oscillations.

封闭在C _60中的开壳氮的光电离

使用耦合通道相关R矩阵方法对开壳式N @ C _60的内富勒烯光电离进行了研究，并对球形球壳富勒烯电势进行了其他修改。特别关注光电离截面的初始状态依赖性。比较表明，在1 s ² 2 s ² 2 p ³（⁴ S）初始状态与亚稳态² D和² P状态之间存在显着差异，并且存在强烈的约束振荡。
