Shell-Model Fragmentation of theSc49Analog Levels

Abstract

The fragmentation of the ${\mathrm{Sc}}^{49}$ analog levels is calculated and is shown to result from two-particle, one-hole $T_{<}$ states that include higher energy bound proton contributions. In addition, the damping widths of the fragmented levels due to three-particle, two-hole couplings $T^{\downarrow }$ and the escape widths $T^{\uparrow }$ are computed. The theoretical analog-level energies and widths are compared with experiment.
