Abstract :
The fp-shell nucleus 52Cr is an even-even nuclei near magic number is with closed neutron shell is at N = 28. It was found that coexistence between spherical and deformed shapes can take place rather predominantly in and near semi-magic or doubly magic nuclei. So this nucleus may provide a valuable insight is into the interplay between single-particle and collective modes of excitation. High-spin states in 52Cr have been studied using 27Al (28Si, 3p) 52Cr fusion evaporation reaction at beam energy of 70 MeV. The level scheme of 52Cr has been extended up to Ex ~ 10 MeV. Spins and parities have been assigned to many of the new levels on the basis of the directional correlations and linear polarization measurements using clover detectors. The band structures are discussed in the framework of cranked Woods-Saxon and microscopic projected deformed Hartree-Fock (HF) models. The prolate-oblate shape coexistence is proposed in 52Cr nucleus.
