Calculated Lifetimes in the Neon Isoelectronic Sequence

Abstract

Calculations of energies and lifetimes of levels for configurations 2s22p53l and 2s2p63l were performed for the Mg, Si, S, Ar, Ca, Ti, V, Cr, Fe, Ni ions. The intermediate coupling scheme was used. The initial energy matrix was derived in the LS-scheme. Relativistic corrections were calculated using the Breit operator. Calculations were made in the framework of the Z-expansion perturbation theory.
