Abstract

We show for the first time that the generalized seniority scheme explains reasonably well the B(E3) systematics for the \((0^+ \rightarrow 3_1^-)\) transitions in the Sn isotopes, which are odd-tensor E3 transitions connecting different seniority states (\(\Delta v = 2\)). Additionally, we also present large scale shell model (LSSM) calculations to support our interpretation. The generalized seniority scheme points to the octupole character of these \(3^-\) states in Sn isotopes.
