Absolute transition probabilities for the first 2(+) states in Pd-110,Pd-114 were measured using the recoil distance Doppler shift technique following projectile Coulomb excitation at intermediate beam energy. This technique was applied for the first time to projectiles produced in a primary fragmentation reaction, which get Coulomb excited in a secondary reaction. The Pd-110 data was used to check the novel experimental technique as well as the data analysis procedure, which is based on the examination of gamma-ray line shapes. Whereas the measured B(E2) value for Pd-110 agrees very well with the literature, the value obtained for Pd-114 differs considerably. The new experimental data are compared to calculations in the framework of the Interacting Boson Model. The data are also used to test the novel concept of valence proton symmetry, which allows for extrapolation of nuclear properties to very neutron-rich nuclei.
