Coulomb excitation is a powerful tool to determine reduced transition probabilities of exotic nuclei far off stability. Therefore, the radioactive ion beam impinges onto target nuclei with well-known transition probabilities. Typically, unknown transition probabilities of the projectiles are determined relative to the established target values and detailed knowledge of standard target nuclei like 104Pd is key. The B(E2:2+ → 0+) value of the first excited state in 104Pd and the correlated quadruple moments have so far only been investigated via Coulomb excitation. A precise lifetime measurement, as a complementary approach to determine reduced transition strengths in 104Pd and to minimize the systematic errors, was performed at the FN Tandem accelerator of the IKP Cologne employing the Recoil-Distance Doppler-Shift (RDDS) method. Excited states of 104Pd were populated via the fusion evaporation reaction 96Zr(12C,4n)104Pd at 55 MeV upto 18 ℏ. Measured lifetimes in 104Pd will be presented and reduced transition probabilities will be compared to Coulomb excitation results.
