Abstract

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.
