The reactions 152Sm(α,3n) at 37 MeV and 124Sn(36S,α3n) at 165 MeV were used to produce high-spin states in the transitional rare-earth nucleus 153Gd. Significant extensions in angular momentum and excitation energy with respect to earlier work were achieved and several new rotational sequences were observed. The rotational behavior of 153Gd is described in terms of quasiparticle assignments and the observed alignment properties are analyzed within the framework of the cranked shell model. Detailed comparisons with other N=89 nuclei are presented. These have led to corrections to the 157Er level scheme
