128Cd is only two proton and two neutron holes away from the doubly magic nucleus 132Sn. The proximity to this r-process waiting-point nucleus underlines its importance for the understanding of nucleosynthesis. So far, contradicting theoretical predictions for the B(E2,0+->2+) value of 128Cd exist. While shell model calculations conclude an almost spherical shape of 128Cd, beyond mean field calculations predict an already considerable quadrupole collectivity. In this contribution the experimental details of the Coulomb excitation of 128Cd at REX-ISOLDE (experiment IS477) will be presented. Furthermore the current status of the analysis to determine the transition strength of the ground state into the first excited 2+ state will be shown. This project is supported by BMBF (No. 06 DA 9036I) and EU through ENSAR (No. 262010).
