摘要
A fast data acquisition method based on pulse width analysis was developed for gamma-ray spectroscopy with an NaI(Tl) detector. The new method was tested in experiments with standard gamma-ray sources and pulsed neutron beam from a spallation neutron source. Pulse height spectra were successfully reconstructed from pulse width distribution by use of an energy calibration curve. The Au-197(n,gamma) Au-198 cross section was measured by this method to test the viability. The obtained experimental cross section showed a good agreement with a calculation using the resonance parameters of JENDL-4.0.
