Abstract

The odd-odd ${}^{146}{Tb}$ nucleus has been investigated using the ${}^{115}{In} ({}^{34}S, 3 n)$ reaction at 140 MeV incident energy using an array of eight Compton-suppressed Clover detectors. Based on the observed $γ − γ$ coincidences, the level structure of ${}^{146}{Tb}$ has been extended up to $E_{x} \sim 10 MeV$ . Linear polarization measurements have been combined with angular correlations of the observed $γ$ rays to assign the electromagnetic nature to the transitions. Probable origin of a cascade of $M 1$ transitions observed around 8 MeV excitation energy has been discussed.
