Abstract
Yrast and yrare states in the nucleus have been studied in the reaction Ar,5p) by measuring γγ coincidences and directional correlation orientation with the OSIRIS array. In addition, γ-ray singles angular distributions have been taken with the reaction Cl,4p). Up to the highest spins observed (37/,33/), the states identified line up with the ones predicted by the spherical shell model, taking into account three proton particles and two neutron holes in the and single-particle orbits. The shell model also reproduces most of the measured branching and E2/M1 mixing ratios. The mean lifetime of the 2152 keV 17/ yrast state was determined as 0.74(7) ns.
