Photoexcitation of 76Ge — Ronald Schwengner1, Konrad Schmidt1, Kai Zuber2, •Hans F. R. Hoffmann2, Marie Pichotta2, and Steffen Turkat2 — 1Helmholtz-Zentrum Dresden-Rossendorf, 01328 Dresden, Germany — 2Institute of nuclear and particle physics, TU Dresden, 01069 Dresden, Germany
The dipole strength of the nuclide 76Ge was studied in photon-scattering experiments using bremsstrahlung produced with electron beams of energies of 7.8 and 12.3 MeV which were delivered by the electron linear accelerator of high brilliance and high brightness (ELBE).
In total, 210 levels up to an excitation energy of 9.4 MeV were identified and a spin J = 1 was assigned to most of them. The quasi-continuum of unresolved transitions was included in the analysis of the spectra and the intensities of branching transitions were estimated on the basis of simulations of statistical γ-ray cascades. The photoabsorption cross section up to the neutron-separation energy was determined.
The experimental procedure and results will be discussed including some implication on 76Ge 0νββ experiments.
