Inconsistencies between lifetime and polarizability measurements in Cs
Electric-dipole matrix elements for 6p-nd, n=5, 6, 7 transitions in cesium
are calculated using a relativistic all-order method. The resulting matrix
elements are used to evaluate 5d lifetimes and 6p polarizabilities. The data
are compared with experimental lifetime and polarizability measurements made by
different groups. Domination of the 6p scalar polarizabilities by 5d-6p dipole
matrix elements facilitates an exacting consistency check of 5d lifetime and 6p
polarizability data. Values of 5d-6p matrix elements obtained from experimental
5d lifetime data are found to be inconsistent with those inferred from 6p
polarizabilities derived from experimental Stark shift data. Our ab initio
calculated 6p polarizabilities agree well with experimental determinations.Comment: 5 pages, submitted to Physical Review
