The reduced transition probabilities between the first excited 2+ state and the 0+ ground state, B(E20+-->2+), have been measured in 106,108,110Sn using sub-barrier Coulomb excitation in inverse kinematics at REX-ISOLDE. The results are, B(E20+-->2+) = 0.220(22), 0.226(17), and 0.228(32)e2b2, for 110Sn, 108Sn, and 106Sn, respectively. The results for 106,108Sn are preliminary. De-excitation γ-rays were detected by the MINIBALL Ge-array. The B(E2) reveals detailed information about the nuclear wave function. A shell model prediction based on an effective CD-Bonn interaction in the ν(0g7/2,2s,1d,0h11/2) model space using eeffν = 1.0 e follows the experimental values for the neutron rich Sn isotopes, but fails to reproduce the results presented here.
