Measurement of the Neutron Capture Cross-Sections for Dy and Hf between 0.001 eV and 50 keV Using Total Energy Absorption Detector

Source

The capture cross sections of Dy and Hf were measured in the energy region from 0.001 eV to 50 keV by using the neutron time-of-flight method with a 46 MeV electron linear accelerator of the Research Reactor Institute, Kyoto University. An assembly of Bi4Ge3O12(BGO) scintillators, which was placed at a distance of 12.7 ± 0.02 m from the neutron source, was employed as a total absorption detector for the prompt capture gamma-ray measurement on the sample. For the capture cross section of Dy, the existing experimental data and the evaluated data in ENDF/B-VI and JEF-2.2 are close to the present result. For the Hf capture cross section, the previous experimental data and the evaluated data in JENDL-3.2 and ENDF/B-VI are in general agreement with the present measurement.
