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.

Effective axial-vector strength within proton-neutron deformed quasiparticle random-phase approximation
Delion, D. S.; Dumitrescu, A.; Suhonen, J. (American Physical Society, 2019)We use the available experimental Gamow-Teller β− and β+/EC (electron-capture) decay rates between 0+ and 1+ ground states in neighboring even-even and odd-odd nuclei, combined with 2νββ half-lives, to analyze the influence ... -

(American Physical Society, 2018)The occurrence of octupolar shapes in the Ba isotopic chain was recently established experimentally up to N = 90 . To further extend the systematics, the evolution of shapes in the most neutron-rich members of the ... -
