THE PHYSICS OF HOLLOW LITHIUM ATOM

The saddle-point variation method and saddle-point complex-rotation me thod are used to study the multiply-excited atomic lithium. Using mult iconfiguration interaction wave function, the energy of these states a re calculated to high precision. Relativistic corrections are included . The total as well as partial Auger width are obtained. The result of our theoretical calculation is compared with the recent high precisio n experiments in the literature.
