Abstract

High-resolution -ray spectroscopy of is performed with the Advanced GAmma Tracking Array, following deep-inelastic processes induced by an beam on a target. Six states are newly identified, which together with the three known excitations exhaust all negative-parity excited states expected in below the neutron threshold. Spin and parities are proposed for all located states on the basis of decay branchings and comparison with large-scale shell-model calculations performed in the p-sd space, with the YSOX interaction. Of particular interest is the location of the and excitations, which provide strong constrains for cross-shell p-sd matrix elements based on realistic interactions and help to simultaneously reproduce the ground and first-excited states in and , for the first time. Understanding the structure may also have significant impact on neutron-capture cross-section calculations in r-process modeling including light neutron-rich nuclei.
