| dc.description.abstract | The Coulomb excitation of 102Ru was performed with beams of 12C and 16O ions. The beam particles scattered at forward angles were momentum analyzed with a magnetic spectrograph. The resolution achieved enabled the populations of the 2+ 1 state, the unresolved 2+ 2 /4+ 1 , and 2+ 4 /3− 1 , doublets of states, and the 3− 2 state to be determined as a function of the scattering angle. These populations are compared with GOSIA calculations, yielding B(E2; 2+ 1 → 0+ 1 ) = 41.5 ± 2.3 W.u., B(E2; 2+ 2 → 0+ 1 ) = 1.75 ± 0.11 W.u., B(E3; 3− 1 → 0+ 1 ) = 31.5 ± 3.5 W.u., and B(E3; 3− 2 → 0+ 1 ) = 6.8 ± 0.5 W.u. The B(E3; 3− 1 → 0+ 1 ) value is significantly larger than previously measured. The weakly populated 2+ 3 state, presumed to be a member of the band built on the 0+ 2 state, was observed clearly for a single angle only, and a fit to its population results in B(E2; 2+ 3 → 0+ 1 ) = 0.053 ± 0.011 W.u. Using the known γ -ray branching ratios for the 2+ 3 level, the B(E2; 2+ 3 → 0+ 2 ) value is calculated to be 18 ± 4 W.u., substantially less than the B(E2; 2+ 1 → 0+ 1 ). This suggests that the deformation of the 0+ 2 state is lower than that of the 0+ 1 state. The results are compared with beyond-mean-field calculations with the Gogny-D1S interaction using the symmetry-conserving configuration-mixing method. | en_US |
