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 1 2^-[521], 5 2^-[512] and (mixed) 7 2⁺[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.
