4 Ab initio determination of the lifetime of the 6 2 P 3 / 2 state for 207 Pb + by relativistic many - body theory
نویسندگان
چکیده
Relativistic coupled-cluster(RCC) theory has been employed to calculate the lifetime of the 62P3/2 state of single ionized lead(Pb) to an accuracy of 3% and compared with the corresponding value obtained using second order relativistic many-body perturbation theory(RMBPT). This is one of the very few applications of this theory to excited state properties of heavy atomic systems. Contributions from the different electron correlation effects are given explicitly.
