LIFETIMES AND POLARIZABILITIES OF LOW LYING S, P AND D STATES OF FRANCIUM

The lifetimes as well as the scalar and tensor polarizabilites are computed for over 60 low lying S, P and D states of francium using a Coulomb approximation. The result for the 7 P 3/2 state lifetime agrees very closely with a recent measurement while the scalar polarizability of the ground state i...

Description
Summary:The lifetimes as well as the scalar and tensor polarizabilites are computed for over 60 low lying S, P and D states of francium using a Coulomb approximation. The result for the 7 P 3/2 state lifetime agrees very closely with a recent measurement while the scalar polarizability of the ground state is estimated to be substantially lower than previously predicted. No other lifetime or polarizability determinations were found in the literature. This data will facilitate future studies of francium spectroscopy.
