| Abstract: | The energies and widths of the 2s2psp 2S triply excited hollow states of lithiumlike ions are calculated with multichannel saddle-point and saddle-point complex-rotation methods. Relativistic effects are computed with first-order perturbation theory. The widths are studied with one open channel at a time as well as fully coupled open channels. The radiative transition rates are also calculated. These results are compared with the theoretical data in the literature. |
