Shape coexistence in 178Hg
Abstract
Lifetime measurements of excited states in
178
Hg
have been performed using the
103
Rh
(
78
Kr
,
p
2
n
)
reaction at a beam energy of 354 MeV. The recoil-decay tagging (RDT) technique was applied to select the
178
Hg
nuclei and associate the prompt
γ
rays with the correlated characteristic ground-state
α
decay. Lifetimes of the four lowest yrast states of
178
Hg
have been determined using the recoil distance Doppler-shift (RDDS) method. The experimental data are compared to theoretical predictions with focus on shape coexistence. The results confirm the shift of the deformed prolate structures to higher lying states but also indicate their increasing deformation with decreasing neutron number.
