Abstract
Low-spin single quasineutron levels in and have been studied following the () and () reactions. A combined Si telescope and high-purity germanium array was utilized, allowing and coincidence measurements. Almost all of the established low-excitation-energy, low-spin structures were confirmed in both and . Several new levels and numerous new rays are observed in both nuclei, particularly for MeV. Residual effects of a neutron subshell closure at are observed in the form of a large excitation energy gap in the single quasineutron level schemes.
