Transient field measurements of first-excited state g-factors in^188,190,192Os

Abstract

Transient-field precessions were measured simultaneously for the 21+ states of188,190,192Os as ions of these nuclei traversed a thin polarized iron foil. In contrast with most earlier measurements, the relative gyromagnetic ratios deduced here are independent of the level lifetimes. Emphasis is placed upon determination of the g-factor of the first excited state in190Os, as disparities in measurements of the lifetimes of this level have led to uncertainties in its g-factor.
