Lifetimes of low-spin excited states in 102Mo populated in a 100Mo(18O,16O)102Mo two-neutron transfer reaction were measured using the recoil-distance Doppler-shift technique at the Cologne FN Tandem accelerator. Lifetimes of the 2+1, 4+1, 6+1, 0+2, 2+γ, 3+γ states and one upper limit for the lifetime of the 4+γ state were obtained. The energy levels and deduced electromagnetic transition probabilities are compared with those obtained within the mapped interacting boson model framework with microscopic input from Gogny mean-field calculations. With the newly obtained signatures a more detailed insight in the γ softness and shape coexistence in 102Mo is possible and discussed in the context of the Z≈40 and N≈60 region. The nucleus of 102Mo follows the γ soft trend of the Mo isotopes. The properties of the 0+2 state indicate, in contrast with the microscopic predictions, shape coexistence which also occurs in other N=60 isotones.

%X Lifetimes of low-spin excited states in 102Mo populated in a 100Mo(18O,16O)102Mo two-neutron transfer reaction were measured using the recoil-distance Doppler-shift technique at the Cologne FN Tandem accelerator. Lifetimes of the 2+1, 4+1, 6+1, 0+2, 2+γ, 3+γ states and one upper limit for the lifetime of the 4+γ state were obtained. The energy levels and deduced electromagnetic transition probabilities are compared with those obtained within the mapped interacting boson model framework with microscopic input from Gogny mean-field calculations. With the newly obtained signatures a more detailed insight in the γ softness and shape coexistence in 102Mo is possible and discussed in the context of the Z≈40 and N≈60 region. The nucleus of 102Mo follows the γ soft trend of the Mo isotopes. The properties of the 0+2 state indicate, in contrast with the microscopic predictions, shape coexistence which also occurs in other N=60 isotones.
