Electron–Gamma Spectroscopic Studies in ${}^{{131}}$Xe from the ${}^{{131}}$I Decay

Abstract

Gamma transitions in ${}^{131}$Xe have been studied in the relatively long lived beta decay of ${}^{131}$I using well calibrated large volume High Purity Germanium (HPGe) gamma spectroscopy system and a high transmission Mini-Orange electron transporter. Relative gamma and conversion electron intensities are used to determine internal conversion coefficients, for multipolarity assignments of gamma transitions and multipole mixing ratios and $B(E2)$ values for most of the transitions in ${}^{131}$Xe with good precision. Most of the data on conversion coefficients are being reported for the first time.
