Measurements of Neutron Total Cross-Section of Natural Silver in the Energy Region from 0.01 to 10 eV

다국어 초록 (Multilingual Abstract)

We measured the neutron total cross-section of natural Ag in the energy region from 0.01 eV to 10 eV by the neutron time-of-flight method with a data acquisition system based on the flash analog to digital converter. The experiment was performed at Pohang Neutron Facility, which consists of a 100 MeV electron linac, a water-cooled Ta-target with a water moderator and a 6Li-ZnS(Ag) scintillator located at 11 m long time-of-flight path. The background level has been determined by using notch filters, which consist of Co, In, Dy and Cd plates. The present averaged neutron total cross-sections in the thermal neutron energy region are compared to those from the previous measurements and the evaluated data. The differences between the present and the evaluated averaged cross-sections were less than 2%.
