Decays ofPb194,195,196

Abstract

Decay properties of ${}_{}{}^{194,195,196}{}_{}{}^{}\mathrm{Pb}$ were studied using singles and coincident $\gamma$-ray spectroscopy. Sources were produced by the 95 MeV ${}_{}{}^{197}{}_{}{}^{}\mathrm{Au}$(${}_{}{}^6{}_{}{}^{}\mathrm{Li}$,$\mathrm{xn}$) reactions. No direct evidence for the decay of a low-spin isomer of ${}_{}{}^{195}{}_{}{}^{}\mathrm{Pb}$ was observed. Several new levels were observed in ${}_{}{}^{195,196}{}_{}{}^{}\mathrm{Tl}$, and are interpreted in terms of a rotational model.
