MEASUREMENT OF GAMMA-RAY ENERGY DUE TO INELASTIC NEUTRON SCATTERING

摘要

F-0782 MEASUREMENT OF GAMMA-RAY ENERGY DUE TO INELASTIC NEUTRON SCATTERING A source of fast neutrons is pulsed to irradiate the formations surrounding a borehole with neutrons to produce inelastic neutron scattering in metallic materials located within the formations. Gamma-rays emitted from the formations in response to the inelastic neutron scattering from the metallic materials is detected as an indication of the presence of such materials within the formations.
