description

Abstract: The neutron-deficient mercury isotopes, 184 , 186 Hg, were studied with the recoil distance Doppler-shift method using the Gammasphere array and the K ̈ oln plunger device. The differential decay curve method was employed to determine the lifetimes of the yrast states in 184 , 186 Hg. An improvement on previously measured values of yrast states up to 8 + is presented as well as first values for the 9 3 state in 184 Hg and 10 + state in 186 Hg. B ( E 2) values are calculated and compared to a two-state mixing model which utilizes the variable moment of inertia model, allowing for extraction of spin-dependent mixing strengths and amplitudes. peerReviewed
