Abstract

The model of a single-$j$ nucleon coupled to an asymmetric rotor is applied to new experimental results on yrast bands in $^{187}\mathrm{Ir}$, $^{195}\mathrm{Au}$, and $^{197}\mathrm{Tl}$. The core asymmetry is shown to account for systematic trends in the high-spin spectra. Information on the shape dependence of moments of inertia is obtained which supports the idea of nuclear flow of irrotational type.
