The time evolution of the decay of high-spin, normal deformed structures in
Hg-193,Hg-194 was Studied by measuring, in the Gammasphere array, the Dopp
ler shift attenuation of selected transitions depopulating various bands. T
he data suggest that a fraction of states feeding selective yrast levels is
non-collective in nature and show resemblance to A = 150 nuclei where shap
e polarizing effects have been linked to particles occupying high-j orbital
