Evidence for Asymmetric Shapes from High-Spin Odd-ASpectra

Abstract
The model of a single-j nucleon coupled to an asymmetric rotor is applied to new experimental results on yrast bands in Ir187, Au195, and Tl197. 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.
