Abstract
The low-energy spectra of186Hg and184Hg are interpreted by a mixing of spherical and deformed states for angular momentum I=2, 4. In order to establish agreement between experimental results on186Hg and184Hg and potential calculations, a stronger isospin dependence of the pairing interaction is introduced. The existence of shape-isomeric states for186Hg,184Hg with a life-time ≈10−8 sec is concluded from the model. The particle-vibration coupling is discussed as the probable origin for the odd-even staggering of the ground-state deformation.
