Collectivity at N = 40 in neutron-rich {sup 64}Cr.
9Be-induced inelastic scattering of 62,64,66Fe and 60,62,64Cr was performed at intermediate beam energies. Excited states in 64Cr were measured for the first time. Energies and population patterns of excited states in these neutron-rich Fe and Cr nuclei are compared and interpreted in the framework of large-scale shell-model calculations in different model spaces. Evidence for increased collectivity and for distinct structural changes between the neighboring Fe and Cr isotopic chains near N=40 is presented.
