Abstract

We calculate the g factor of the 6s6pP03 state of 199 and 201 mercury isotopes using a relativistic high-precision all-order method that combines the configuration interaction and the coupled-cluster approaches. Our values g(Hg199)=0.9485(49)×103 and g(Hg201)=0.3504(18)×103 are in agreement with the experimental measurements within the 0.5% theoretical uncertainty. We also calculate the hyperfine quenching rate of the 6s6p3P0 state in Hg199 and Hg201 and determine its lifetime to be 1.3 and 1.9 s, respectively.
