Lifetime measurements to investigate γ softness and shape coexistence in ¹⁰²Mo

NUCLEAR REACTIONS ¹⁰⁰Mo(¹⁸O, ¹⁶O)¹⁰²Mo, E=52 MeV; measured Eγ, Iγ, γγ-coin, T_1/2 of levels by recoil-distance Doppler-shift method using an array of eleven HPGe detectors, and Cologne Plunger device at the Cologne FN Tandem accelerator facility. ¹⁰²Mo; deduced levels, J, π, B(E2), B(M1), E0 transition probability; calculated deformation-energy surface in the (β, γ) plane. Comparison of levels and B(E2) with mapped interacting boson model (IBM) calculations, with microscopic input from Gogny mean-field. Systematics of 0+ and first 2+ states and B(E2) values in N=52-64, Sr, Zr, Mo and Ru isotopes. Discussed shape coexistence and γ-softness.
