Abstract

The low-lying excited states of ${}^{46}S$ and ${}^{47}S$ were investigated using knockout reactions on a liquid hydrogen target combined with $γ$ -ray spectroscopy. Four new transitions were observed in ${}^{46}S$ , and a single $γ$ ray was identified in ${}^{47}S$ . Comparison with shell-model calculations allowed the assignment of the observed transitions to specific theoretical levels. The energies of the $4_{1}^{+}$ and $2_{2}^{+}$ states in ${}^{46}S$ suggest the presence of triaxial deformation.
