Abstract

Abstract: A Monte Carlo simulation of the energy spectrum of the α particles emitted from a 238 U3 O8 sample is performed. Through comparing the simulated and measured energy spectra of the α particles, the non-uniformity of the 238 U3 O8 sample is obtained, and then the number of 238 U target nuclei is determined. Using the obtained non-uniformity, a Monte Carlo simulation is developed to simulate the energy spectrum of neutron induced fission fragments. The simulated and measured energy spectra of neutron induced fission fragments agree well with each other. Highlights: With the experiments and simulations, the amount of 238 U target nuclei are decided. The simulated energy spectrum accords well with the measured one. The effect of the non-uniformity on the fission energy spectrum is proved to be significant.
