U-238 Neutron Capture Gamma Cascade Generation and Transport Simulation for Capture Tank Response
Abstract
A computer analysis has been performed to evaluate the energy dependent response of a capture tank to the gamma rays emitted in the cascades of the excited U-239 nucleus. This model determines the energies of the gamma- ray cascades, the order of emission of the gamma rays in a cascade, and the gamma-ray multiplicity of the cascades using Monte Carlo techniques. A capture tank responds to the combined effect of the various gamma rays emitted in the cascade. Examined is the energy deposition in a capture tank by the cascades generated in resonant (surface) capture and off-resonant (volumetric) capture, with and without internal conversion. Off-resonant capture deposits, on the average, less energy than resonant capture, due to self-shielding of the gamma-rays in the capture sample. Internal conversion has negligible effect on the average cascade energy deposited in the capture tank.
