Abstract
Electric dipole matrix elements for , , , , transitions in cesium are calculated using a relativistic all-order method. The resulting matrix elements are used to evaluate lifetimes and polarizabilities. The data are compared with experimental lifetime and polarizability measurements made by different groups. Domination of the scalar polarizabilities by dipole matrix elements facilitates an exacting consistency check of lifetime and polarizability data. Values of matrix elements obtained from experimental lifetime data are found to be inconsistent with those inferred from polarizabilities derived from experimental Stark shift data. Our calculated polarizabilities agree well with experimental determinations.
