Description

The relativistic linked-cluster many-body perturbation theory (RLCMBPT) has been used to investigate the hyperfine properties in the excited 7 2P3/2 and 7 2P1/2 states of 221Ra+ ions. Our calculations of the hyperfine constants yield -22.4±0.3 MHz for the 7 2P3/2 state and -265.3±4.0 MHz for the 7 2P1/2 state, in excellent agreement with the experimentally obtained values of -22.4±0.9 and -266.3±1.5 MHz, respectively. The results obtained in this work are compared with those by other theoretical methods and an attempt is made to understand the relationship between the different methods, particularly that between the RLCMBPT procedure adopted in this work and the many-body multiconfigurational Dirac-Fock procedures
