Shape coexistence and high spin states in {sup 52}Cr

High spin states in {sup 52}Cr have been populated by means of the reaction {sup 27}Al({sup 28}Si,3p){sup 52}Cr at a beam energy of 70 MeV and studied with an array, consisting of eight Compton-suppressed clover germanium detectors. Eleven new {gamma} rays have been assigned to {sup 52}Cr and placed in the level scheme. The level structure of {sup 52}Cr has been extended up to E{sub x}{approx_equal}10 MeV. Spins and parities have been assigned to many of the levels on the basis of directional correlations and linear polarization measurements. The band structures are discussed in the framework of cranked Woods-Saxon and deformed Hartree-Fock (HF) models. Both the oblate and prolate orbits are considered for J projection in the HF model. The K=0{sup +} band is properly understood if we consider the J projection from both prolate and oblate orbits and collectivity shown by the K=4{sup +} band to be accounted for by taking the J projection from prolate HF configurations. Thus there is prolate and oblate shape coexistence in {sup 52}Cr.
