Shape coexistence in neutron-deficient Hg isotopes studied via lifetime measurements in Hg-184,Hg-186 and two-state mixing calculations
Abstract
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.
