Title: Photodissociation experiments for p-process nuclei

Abstract

The near-threshold photodissociation of nuclides received an increased attention in recent years due to its relevance for heavy element production in astrophysical scenarios. Therefore, a research program has been started to study photodissociation reactions using energetic bremsstrahlung from the new ELBE electron linear accelerator. Special emphasis was devoted to the neutron deficient nuclei with A{approx_equal}100 which may have been produced in cosmic high-temperature regions by ({gamma},n) ({gamma},p), or ({gamma}, {alpha})-reactions. First data were obtained for the astrophysically important target nucleus 92Mo by observing the radioactive decay of the nuclides produced by bremsstrahlung irradiation at end-point energies between 11.8 and 14.0 MeV. The results are compared to recent statistical-model calculations.
