Knowledge of the exact microscopic structure of the 01
+ ground state and first excited 02
+ state in 150Sm is
required to understand the branching of double β decay to these states from 150Nd. The detailed spectroscopy of 150Sm and 152Gd has been studied using (α,xn) reactions and the γ -ray arrays AFRODITE and JUROGAM II.
Consistently strong E1 transitions are observed between the excited Kπ = 02
+ bands and the lowest negative
parity bands in both nuclei. These results are discussed in terms of the possible permanent octupole deformation
in the first excited Kπ = 02
+ band and also in terms of the “tidal wave” model of Frauendorf.

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 ... -
