Abstract

Level schemes of the proton-rich nuclei, Mn47 (Z=25,N=22) and Cr45 (Z=24,N=21), have been established for the first time. The technique of mirrored one- and two-nucleon knockout reactions was applied to the secondary beams of V48/Mn48 and V47/Cr47 to populate states in Ti47/Mn47 and Sc45/Cr45, respectively. Mirror energy differences (MED) have been studied between the mirrored T=32 states for both mirror pairs and interpreted using both a shell-model approach and a density-functional-theory approach using the no-core configuration-interaction method. MED in this mass region provide a stringent test of the model prescriptions since both fp- and sd-shell orbitals are active and, in Cr45, spherical and well-deformed structures coexist near the ground state. The inclusive and exclusive one-nucleon removal cross sections have been determined for the populated states in Ti47/Mn47 and compared with results from reaction-model calculations.
