Abstract

Two complementary experimental programs have taken place to investigate the origin and evolution of shape coexistence in the light mercury region. Recoil Distance Doppler-shift measurements were performed at the University of Jyvaskyla utilizing the Koln plunger device in conjunction with the JUROGAM + RITU + GREAT setup. In addition, Coulomb excitation measurements of Hg-184,Hg-186,Hg-188 were performed at REX-ISOLDE using the MINIBALL Ge-detector array. The results of the lifetime measurements of the yrast states up to I-pi = 10(+) in Hg-182 are reported. Preliminary analysis of the Coulomb excitation data is also discussed.
