Spin-induced autoionization and radiative transition rates for the (1s2s2p)4PJo states in lithiumlike ions.

Abstract

The saddle-point complex-rotation method in the intermediate LSJ-coupling scheme is used with the Breit-Pauli spin-dependent perturbation operators to compute the spin-induced autoionization rates of the lithiumlike 1s2s2p $^{4}P_{J}^{o}$ states from Z=3 to 18. The radiative transition rates of the J=(1/2 and (3/2 levels are also calculated in the intermediate LSJ-coupling scheme. The combined result yields lifetimes for these levels which are compared with the existing experimental and theoretical data in the literature.
