Energy and Auger Widths of Triply Excited 3p3p3p ²P^o State of Lithium

The high-lying triply excited 3p3p3p ²P^o state of the double hollow lithium atom is studied by using the saddle-point complex-rotation method. The energy and Auger widths of this resonance are calculated. The relativistic corrections and mass polarization are included. The total Auger width is obtained by coupling the important open channels and summing over the other channels. The oscillator strength is also calculated. The results are compared with other theoretical and experimental data in the literature.
