| 摘 要： | In recent years,neutron capture cross sections of Ag,Hf and W relative to that of Au in the energy range from 10 to 100 keV have been measured withtime-of-flight method.Kinematically collimated neutrons were produced by ~7Li(p,n)~7Be reaction with the pulsed 2.5MV Van de Graaff accelerator.Captureevents were detected by two Moxon-Rae detectors.The resolution time of thewhole system,that is,the full-width at half-maximum(FWHM)of the promptgamma-ray peak was 1.60 ns.The total uncertainty is about 7% for most of thedata points.
