Résumé

The Coulomb excitation of Ru102 was performed with beams of C12 and O16 ions. The beam particles scattered at forward angles were momentum analyzed with a magnetic spectrograph. The resolution achieved enabled the populations of the 21+ state, the unresolved 22+/41+, and 24+/31, doublets of states, and the 32 state to be determined as a function of the scattering angle. These populations are compared with gosia calculations, yielding B(E2;21+01+)=41.5±2.3 W.u., B(E2;22+01+)=1.75±0.11 W.u., B(E3;3101+)=31.5±3.5 W.u., and B(E3;3201+)=6.8±0.5 W.u. The B(E3;3101+) value is significantly larger than previously measured. The weakly populated 23+ state, presumed to be a member of the band built on the 02+ state, was observed clearly for a single angle only, and a fit to its population results in B(E2;23+01+)=0.053±0.011 W.u. Using the known γ-ray branching ratios for the 23+ level, the B(E2;23+02+) value is calculated to be 18±4 W.u., substantially less than the B(E2;21+01+). This suggests that the deformation of the 02+ state is lower than that of the 01+ state. The results are compared with beyond-mean-field calculations with the Gogny-D1S interaction using the symmetry-conserving configuration-mixing method.
