2S(2)2P P-2(O) TRIPLY EXCITED-STATE OF HE-

The triply excited 2s(2)2p P-2(0) state of He- is studied by using the saddle-point complex-rotation method. The energy and Auger width of t his resonance are calculated. Relativistic corrections are evaluated w ith the first-order perturbation theory, and the mass-polarization eff ect is also included. The partial Auger widths are calculated for the individual open channels. The total width is obtained by coupling the important open channels and summing over the other channels. These res ults are compared with the theoretical and experimental data in the li terature. [S1050-2947(98)05909-5].
