E1, E2 and M1 transitions between n=3 levels in magnesium-like tungsten

Abstract

Electric dipole (E1) transitions of 3s-3p and 3p-3d, and electric quadrupole (E2) and magnetic dipole (M1)) transitions between fine structure levels of 3s3p and 3p(2) in Mg-like tungsten (W62+) have been studied by multiconfiguration Hartree-Fock (MCHF) method. Multielectron ions of high-Z elements are of interest in atomic structure theory. In this work Breit-Pauli relativistic contributions and correlation effects have been considered. The magnesium-like tungsten lines obtained from this work are compared with other theoretical and experimental results.
