Abstract
The nuclei were populated to high spin following the reaction at a beam energy of 35–40 MeV. The level scheme of has been confirmed and extended to The level scheme of has been extended to The spins and parity of the majority of levels have been determined unambiguously for the first time. The first firm evidence for an intruder band based on the orbital has been observed in In the position of the first state has been determined unambiguously and the presence of a subshell closure at has been confirmed on the basis of the systematics. The properties of both nuclei are compared with total Routhian surface calculations and with previous predictions of subshell closures at and 34. The systematics in the region are discussed in terms of the strong interaction and its effect on the underlying single-particle structure.
