摘要：

Seven triply excited states of lithium-like beryllium and carbon are calculated with the multichannel saddle-point and saddle-point complex-rotation methods. Relativistic effects are included using first-order perturbation theory. The widths are studied with one open channel at a time as well as fully coupled open channels. The predicted Auger branching ratio is compared with the observed spectra. The radiative transition rates are also calculated. These results are compared with the theoretical data in the literature.
