Abstract

Yrast bands in¹⁷⁶Pt (N= 98) and¹⁷⁸Pt have been identified. The level scheme of^l76Pt changes from a quasi-vibrational pattern to that of a well deformed rotor, at very low spins, a behaviour similar to that attributed to shape coexistence in the light Hg isotopes. Analysis of the^176-188pt yrast bands supports a shape coexistence interpretation, the excitation energy of the intruder state behaving as predicted by Wood.
