Abstract

Rare isotope beams of neutron-deficient Sn106,108,110 from the fragmentation of Xe124 were employed in an intermediate-energy Coulomb excitation experiment. The measured B(E2,01+→21+) values for Sn108 and Sn110 and the results obtained for the Sn106 show that the transition strengths for these nuclei are larger than predicted by current state-of-the-art shell-model calculations. This discrepancy might be explained by contributions of the protons from within the Z=50 shell to the structure of low-energy excited states in this region.
