{sup 9}Be-induced inelastic scattering of {sup 62,64,66}Fe and {sup 60,62,64}Cr was performed at intermediate beam energies. Excited states in {sup 64}Cr 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.
