摘要：
A new measurement system to determine the neutron-capture cross-sections of a nucleus at 0.008 <= E-n < 20 MeV has been installed at the 4 MV Pelletron accelerator laboratory at the facility of radiation standards at Japan Atomic Energy Agency. The performance of the new system was studied by measuring the neutron-capture reaction cross-section of Pb-nat using pulsed neutrons from Li-7(p,n)Be-7 at 12 <= E-n <= 103 keV. Prompt gamma-rays from the reaction were detected by means of a highly sensitive anti-Compton Nal(Tl) spectrometer combined with a time-of-flight method. The obtained result demonstrated good sensitivity of the new system to determine the neutron-capture cross-sections of a nucleus at kiloelectron volt neutron energy. (C) 2010 Elsevier B.V.
