【Abstract】 Several different reactions about the interaction of neutrons and nucleus are described. Utilizing the time difference of different reactions, a method that uses double gate subtracting background to measure the inelastic scattering γ spectra is introduced. Utilizing the high and evident characteristic of inelastic scattering γ rays’ energy of C and O, the water and paraffin’s inelastic scattering γ spectra that use C and O as the displaying elements are contained. Such experiments can make students better understand the correlating nuclear physics theory and the principle if the C/O logging and can make students more skillfully use the knowledge of the correlating nuclear electronics.更多还原
