Lifetimes of prolate intruder states in 186Pb and 188Pb and oblate intruder states in 194Po have been determined through recoil distance Doppler-shift lifetime measurements. Deformation parameters of |β2|=0.29(5) and |β2| = 0.17(3) have been extracted from experimental B(E2) values for the prolate and the oblate bands, respectively. The present study addresses the phenomenon of shape coexistence typical for the nuclei near Z=82 and N=104, providing information on configuration mixing of intrinsic structures of the nuclei of interest. The results are compared with the available lifetime data and theoretical results for neutron-deficient Po, Pb, Hg and Pt nuclei. Furthermore, new self-consistent mean-field calculations have been carried out for 194Po.

Correlating Schiff Moments in the Light Actinides with Octupole Moments

Dobaczewski, Jacek; Engel, Jonathan; Kortelainen, Markus; Becker, Pierre (American Physical Society, 2018)

To explore the nature of collective modes in weakly bound nuclei, we have investigated deformation effects and surface flow patterns of isovector dipole modes in a shape-coexisting nucleus, 40Mg. The calculations were ...

(American Physical Society, 2018)

Lifetimes of the first excited 2 + and 4 + states in the extremely neutron-deficient nuclide 172 Pt have been measured for the first time using the recoil-distance Doppler shift and recoil-decay tagging ...

The spectroscopic quadrupole moment of the first 2+ state of 12C has been measured employing the Coulomb-excitation re-orientation technique. Our result of Qs (2+ 1 ) = +9.3+3.5 −3.8 efm2 suggests a larger oblate deformation ...

(Jagellonian University, 2001)

We report here experimental attempts to determine the sign of the electric dipole moment (relative to the electric octupole moment) in the octupole deformed nucleus 226Ra. Sensitivity to this quantity is observed in the ...
