The Landé g factors of highly charged Sn⁴⁷⁺ and Bi⁸⁰⁺ ions

Abstract

The wavefunctions and eigenvalues of the ground states of Sn 47+ ,
and Bi 80+ ions are calculated using the fully relativistic multiconfiguration Dirac-
Hartree-Fock (MCDHF) method. Detailed investigation are carried out to study
the effects of electron correlation, Breit interaction, quantum electrodynamics
(QED), and nuclear recoil. Based on these calculations, the theoretical predictions
for the g factors of the ground states of Sn 47+ and Bi 80+ ions are 1.980429 and
1.934759, respectively. The accuracy of these calculations is expected to be on the
order of 10-5 .
