Abstract:

© 2016 American Physical Society. The distribution of the electromagnetic dipole strength below the neutron separation energy and its influence on the photon distribution after neutron capture were investigated in two experiments for the compound nucleus Cd114. By measuring the photoabsorption cross section at the bremsstrahlung facility γELBE at Helmholtz-Zentrum Dresden-Rossendorf it was possible to deduce the distribution of dipole strength below the neutron separation energy. The de-excitation spectrum after cold-neutron capture in Cd113 was measured at the Budapest Neutron Center. In a combined analysis, the experimentally deduced spectra after photon scattering on Cd114 and the neutron capture in Cd113 were analyzed in terms of electric and magnetic strength functions and nuclear level density with the help of the statistical code γdex.
