Low-lying dipole excitations in the isotopes 113,114Cd

Abstract High-resolution nuclear resonance flourescence (NRF) experiments have been performed on the nuclei 113,114 Cd using bremsstrahlung and Ge-γ-spectrometers. Precise excitation energies, decay widths and decay branching ratios for numerous new levels (dipole excitations) in the energy range 2–4 MeV have been extracted from the measured energy spectra and angular distributions of the scattered photons. The NRF results are compared with IBA calculations and spectroscopic data from particle-induced reactions.
