Systematic study on keV-neutron capture cross sections and capture gamma-ray spectra of Pd isotopes

The capture cross sections and capture gamma-ray spectra of 104,105Pd were measured in the neutron energy region of 15-100 keV as part of a systematic series of measurements. A neutron time-of-flight method was utilized by means of an anti-Compton NaI(Tl) spectrometer and a nsec pulsed neutron source via the 7Li(p,n)7Be reaction. The capture yields were obtained by applying a pulse-height weighting technique to the net capture gamma-ray pulse-height spectra. The capture cross sections of 104,105Pd were derived with errors of less than 5%, using the standard capture cross sections of 197Au. The capture gamma-ray spectra of 104,105Pd were also derived by unfolding the respective observed capture gamma-ray pulse-height spectra. Additionally, the theoretical calculation was made by means of the CCONE computer code. (author)
