Quasi-$\gamma$ band in ${}^{\text{114}}$Te

Abstract

The low-lying non-yrast states in ${}^{114}$Te have been investigated using the Indian National Gamma Array through the fusion-evaporation reaction ${}^{112}$Sn(${}^4$He, 2n) at a beam energy of 37 MeV. Eight new $\gamma$-transitions have been placed in the level scheme to establish the quasi-$\gamma$ band in this nucleus. Spin and parity of several excited states have been assigned from the present spectroscopy measurements. The comparison of experimental results on the observed bands with the Interacting Boson Model (IBM) and Triaxial Projected Shell Model (TPSM) confirming the existence of the quasi-$\gamma$ band structure in the ${}^{114}$Te nucleus.
