Conversion-Electron Spectroscopy of $^{116}$Sn via the $\beta $-decay of $^{116}$In
ORAL
Abstract
Motivated by a study of the prevalence of shape coexistence and collectivity in nuclei at closed shells [1], we have revisited the $^{116}$Sn (Z=50; N=66) nucleus, known to exhibit these characteristics [2], using a $^{116}$In beam produced via the ISOL technique at TRIUMF. The beta decay of $^{116}$In to $^{116}$Sn has been measured using the 8$\pi $ spectrometer and its suite of ancillary detectors. In this presentation we focus on the conversion-electron coincidence spectroscopy of the $^{116}$Sn nucleus, in order to augment and improve the existing knowledge of its structure via the high-statistics spectroscopic data obtained in our experiment. In particular, re-measurements of internal conversion coefficients will be discussed as they pertain to the possibility of mixing of different shapes between bands in $^{116}$Sn. [1] K.
