The reduced transition probabilities between the first excited 2{sup +} state and the 0{sup +} ground state, B(E2;0{sup +}{yields}2{sup +}), have been measured in {sup 106,108,110}Sn using sub-barrier Coulomb excitation in inverse kinematics at REX-ISOLDE. The results are, B(E2;0{sup +}{yields}2{sup +}) = 0.220(22), 0.226(17), and 0.228(32)e{sup 2}b{sup 2}, for {sup 110}Sn, {sup 108}Sn, and {sup 106}Sn, respectively. The results for {sup 106,108}Sn are preliminary. De-excitation {gamma}-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 {nu}(0g{sub 7/2},2s,1d,0h{sub 11/2}) model space using e{sub eff}{sup {nu}} = 1.0 e follows the experimental values for the neutron rich Sn isotopes, but fails to reproduce the results presented here.
