Spin-induced autoionization and radiative transition rates for the (1s2p2p)4PJstates in lithiumlike ions

Abstract
The saddle-point complex-rotation method in the intermediate LSJ coupling scheme is used with the Pauli-Breit spin-dependent perturbation operators to compute the spin-induced autoionization rates of the lithiumlike 1s2p2p 4 PJ states from Z=3 to Z=10. The radiative transition rates of these levels are also calculated in the intermediate LSJ coupling scheme. The combined result yields lifetimes which are compared with the existing experimental and theoretical data in the literature.
