Low-spin single quasi neutron levels in $$^{153}$$Gd and $$^{157}$$Gd have been studied following the $$^{154}$$Gd ($$p,d gamma$$) $$^{153}$$Gd and $$^{158}$$Gd ($$p,d gamma$$) $$^{157}$$Gd reactions. A combined Si telescope and high-purity germanium array was utilized, allowing $$d$$-$$gamma$$ and $$d$$-$$gamma$$-$$gamma$$ coincidence measurements. Almost all of the established low-excitation-energy, low-spin structures were confirmed in both $$^{153}$$Gd and $$^{157}$$Gd. Several new levels and numerous new $$gamma$$ rays are observed in both nuclei, particularly for $$Ex$$ $$geq$$ 1 MeV. Residual effects of a neutron sub shell closure at $$N$$ = 64 are observed in the form of a large excitation energy gap in the single quasi neutron level schemes.
