We have calculated the ratio of bound-state to continuum ..beta..-decay of the potential cosmochronometer /sup 187/Re using Dirac wavefunctions in a Thomas-Fermi atomic potential, including exchange corrections. We found < or approx. = l% bound-state decay for the neutral atom. This differs from a previous calculation using hydrogenic wavefunctions (58%), and from a comparison of published laboratory and geochemical measurements (53% +- 35%).
