Abstract

A new approach for constraining the low-energy part of the electric dipole Photon Strength Function (E 1-PSF) is presented. Experiments at the Darmstadt High-Intensity Photon Setup and the High Intensity View the MathML source-Ray Source have been performed to investigate the decay properties of 130Te between 5.50 and 8.15 MeV excitation energy. In particular, the average γ-ray branching ratio to the ground state and the population intensity of low-lying excited states have been studied. A comparison to the statistical model shows that the latter is sensitive to the low-energy behavior of the E1-PSF, while the average ground state branching ratio cannot be described by the statistical model in the energy range between 5.5 and 6.5 MeV.
