GAMMA-RAY SPECTRA FROM CAPTURE OF FAST NEUTRONS

Journal Article · · Nuclear Phys.

A method to study the spectrum of the gamma rays emitted in radiative capture of fast neutrons has been developed. A sodium iodide scintillation spectrometer was employed, and the use of time-of-flight techniques made it possible to reduce the background of scattered neutrons sufficiently. Nickel, silver, and gold were studied with 0.1Mev neutrons, and a comparison with the gamma-ray spectra from the capture of thermal neutrone was made. The agreement was good for nickel and silver. In the case of gold the relative intensity of the high-energy gamma rays was lower for 0.1-Mev neutrons than for thermal neutrons. (auth)
