Measurements of keV-Neutron Capture Cross-Sections and Capture γ-rays of 105Pd

Abstract

The neutron capture cross-sections and capture γ-rays of 105Pd were measured for keV-neutron using the 3-MV Pelletron accelerator of the Research Laboratory for Nuclear Reactors at the Tokyo Institute of Technology. Pulsed neutrons were produced from the 7Li(p,n)7Be reaction, and the incident neutron spectrum on a capture sample was measured by neutron time-of-flight method with a 6Li-glass detector. The capture γ-rays were detected with a large anti-Compton NaI(Tl) γ-ray spectrometer. A pulse-height weighting technique was applied to measure the capture γ-ray pulse-height spectra to derive capture yields. The capture cross-sections were obtained by using the standard capture cross-section of 197Au. And we obtained the γ-ray energy spectrum of capture γ-ray by the pulse-height unfolding method. The present results were compared with the previous measurements and the evaluated data of ENDF/B-VII, JEFF-3.1, and JENDL-3.3.
