Abstract

The 149Sm(32S, 4n) 177Pt reaction has been used to populate excited states in the neutrondeficient nucleus 177Pt. Rotational bands based on intrinsic states assigned to the 12[521], 52[512] and (mixed) 72+[633] Nilsson configurations have been observed. In contrast to the neighbouring even isotope 176Pt, anomalies attributed to shape coexistence at low spin have not been observed. Implications for the deformation of 177Pt are discussed together with the systematics of intrinsic states in this region, and alignments and other properties of N = 99 nuclei.
