Dipole and quadrupole strength distribution of 204 Pb was investigated via a nuclear resonance fluorescence experiment using bremsstrahlung produced using an electron beam at a kinetic energy of 10.5 MeV at the linear accelerator ELBE. We identified 136 states resonantly excited at energies from 3.6 to 8.4 MeV. The present experimental results were used to investigate the E1 transition probabilities by comparison with predictions from the quasiparticle-phonon model (QPM) with the self-consistent energy-density functional (EDF).

Keywords: Nuclear structure; photon scattering; nuclear resonance fluorescence; electromagnetic transition strengths; quasiparticle-phonon model.
