Abstract

The structure of neutron-rich isotopes Cr60 and Cr62 was studied via proton inelastic scattering in inverse kinematics. The deformation lengths (δ) for Cr60 and Cr62 were extracted as 1.12(16) and 1.36(14)fm, respectively, providing evidence for enhanced collectivity in these nuclei. An excited state at 1180(10) keV in Cr62 was identified for the first time. We adopted 4+ as its spin and parity, leading to the rapid increase of the Ex(4+)/Ex(2+) ratio, which indicates the development of large deformation in Cr62 near N=40. Importance of the admixture of the gd-shell component above N=40 is also discussed by comparing with a modern shell model calculation.

N2 - The structure of neutron-rich isotopes Cr60 and Cr62 was studied via proton inelastic scattering in inverse kinematics. The deformation lengths (δ) for Cr60 and Cr62 were extracted as 1.12(16) and 1.36(14)fm, respectively, providing evidence for enhanced collectivity in these nuclei. An excited state at 1180(10) keV in Cr62 was identified for the first time. We adopted 4+ as its spin and parity, leading to the rapid increase of the Ex(4+)/Ex(2+) ratio, which indicates the development of large deformation in Cr62 near N=40. Importance of the admixture of the gd-shell component above N=40 is also discussed by comparing with a modern shell model calculation.
