Abstract

Excited low-spin states in Mo-96 and Mo-98 have been studied in gamma gamma angular correlation experiments in order to determine spins and multipole mixing ratios. Furthermore, from a Doppler lineshape analysis effective lifetimes tau in the femtosecond range were obtained. The experimental data show a complex spectrum due to configuration mixing, which is confirmed by Interacting Boson Model calculations based on a Skyrme energy density functional. The M1-transition strengths of transitions depopulating excited 2(+) states to the first 2(+) state are discussed in terms of the proton neutron mixed symmetry. (C) 2016 Elsevier B.V.
