Lifetime Measurements and Coulomb Excitation of Light Hg Nuclei

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 Jyväskylä utilizing the Köln plunger device in conjunction with the
JUROGAM
+
RITU
+
GREAT
setup. In addition, Coulomb excitation measurements of
184,186,188
Hg
were performed at REX‐ISOLDE using the MINIBALL Ge‐detector array. The results of the lifetime measurements of the yrast states up to
𝐼
𝜋
= 10
+
in
182
Hg
are reported. Preliminary analysis of the Coulomb excitation data is also discussed.
