Parametrization of two-body perturbation on atomic fine and hyperfine structure. The configuration (6p)3 in the bismuth atom

Abstract

A method of simultaneous parametrization of one- and two-body interactions on atomic hyperfine structure of configurationl N is proposed and applied for the analysis of the configuration (6p)3 in the bismuth atom. For this purpose, the hyperfine structure splittings of the levels2D 3 2/0 ,2D 5 2/0 and2P 1 2/0 were measured. The finally obtained values of HFS parameters are: for one-body parameters (in MHz):a 01 =2,537(9),a 12 =5,182 (12),a′10=−2,019(10),b 02 =−3,198(53),b 11 =2,816(54); for two-body parameters (in MHz):x ′/01 ,2=284(3),x ′/12 ,2=581(5),x ′/12 ,2=170(70),x ′/02 ,2=−359(36),x ′/02 ,2=−33(100). The value of the quadrupole moment of the nucleus 83 209 Bi is also discussed.
