Lifetimes of yrast states in {sup 180}Hg up to the 8{sup +} state and of the 9{sup -} state have been extracted from recoil-decay tagged {gamma}-ray spectra by using the recoil distance Doppler-shift method. In addition, lifetimes of yrast states up to the 10{sup +} state in {sup 182}Hg have been extracted from recoil-gated {gamma}{gamma}-coincidence spectra. The present study addresses the evolution of collectivity of two competing shapes in neutron-deficient Hg nuclei as a function of A and the configuration mixing at low spin.
