Abstract
Low-spin single quasineutron levels in Gd153 and Gd157 have been studied following the Gd154(p,d-γ)Gd153 and Gd158(p,d-γ)Gd157 reactions. A combined Si telescope and high-purity germanium array was utilized, allowing d-γ and d-γ-γ coincidence measurements. Almost all of the established low-excitation-energy, low-spin structures were confirmed in both Gd153 and Gd157. Several new levels and numerous new γ rays are observed in both nuclei, particularly for Ex≥1 MeV. Residual effects of a neutron subshell closure at N=64 are observed in the form of a large excitation energy gap in the single quasineutron level schemes.
