Abstract

The electromagnetic structure of45Sc at low excitation energy was investigated via low-energy Coulomb excitation at the Heavy Ion Laboratory (HIL) of the University of Warsaw and at the Inter-University Accelerator Centre (IUAC) in New Delhi. A set of reduced E2, E3, and M1 matrix elements was extracted from the collected data using the GOSIA code. The reduced transition probability B(E2; 11/2 → 7/2) has been determined, allowing us to deduce the lifetime of the 11/2 state at 1237 keV. In addition, the upper limit on the reduced transition probability B(E3; 7/2 → 5/2+) has been determined for the first time. New large-scale shell-model and beyond-mean-field calculations were performed to interpret the structure of this nucleus.
