High-spin yrast structure of 43Sc

High-spin yrast states in 43Sc were investigated by using in-beam γ-ray technique with the 27Al(19F,p2n) reaction at 50 MeV. The positive-parity rotational band built on the 152-keV Jπ = 3/2+ state has been extended up to the terminating Jπ = (27/2+) state. Several fast transitions feeding to the oblate-deformed Jπ = 19/2− isomer have been also identified. the character of the observed levels and transition rates were discussed in comparison with the shell-model calculations.
