Theoretical analysis of autoionization states for B-like ions

Abstract

Autoionization levels 1s 2s2 2p2, 1s 2p4 and 1s 2s 2p3 of B-like ions were theoretically investigated for Z= 5–100. Calculation was made using perturbation theory over 1/Z. Relativistic corrections were taken into account in limits of Breit operator. Behaviour of radiative transition probabilityA, autoionization rate Γ and level lifetime τ was considered fromZ = 5 up toZ = 100 in detail for configurations 1s 2s2 2p2, 1s 2p4 withJ = 1/2.
