Abstract
A method for determination of atomic lifetimes from the value of dispersion coefficient of molecular potentials correlating to two ground-state atoms is proposed. The method is illustrated with atomic Cs using deduced from high-resolution Feshbach spectroscopy. The following lifetimes are determined: and The underlying electric-dipole matrix elements are required for a refined analysis of parity violation in We also obtain static polarizability of the Cs ground state, atomic units. It is demonstrated that the uncertainties may be considerably reduced as the coefficient is constrained further.
