Shell-model description of heavier 1f7/2 nuclei

Abstract

Natural parity states of odd-A and even–even nuclei in the middle and in the second half of the 1f7/2 shell are described by shell-model calculations in the full pf configuration space. Multi-quasiparticle rotational bands and, in some cases, band crossings have been revealed. The ground-state bands experience a change from collective to non-collective regime, approaching the termination in the 1fn7/2 space. Evidence of the vibrational γ-band is discussed in 52Fe.
