Low-spin single quasineutron levels in 153Gd and 157Gd have been studied following the 154Gd(p,d-ɣ)153Gd and 158Gd(p,d-ɣ)157Gd reactions. A combined Si telescope and high-purity germanium array was utilized, allowing d-ɣ and d-ɣ-ɣ coincidence measurements. Almost all of the established low-excitation-energy, low-spin structures were confirmed in both 153Gd and 157Gd. Several new levels and numerous new ɣ 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. [ABSTRACT FROM AUTHOR]
