Abstract

In this paper, the neutron- material interaction was simulated and caculated. The simulation was based on the Monte-Carlo method and Matlab sofware tool. The processes of moderation and thermalization of neutron in material were estimated. From the simulating results some parameters such as spectrum of neutron after transfering through material, the averaged number of collisions for thermalizing neutron, the path of neutron in material was calculated and showed. The simulation and calculation in this paper match with the simulating results of the research from the School of physics, The University of New South Wales, Sydney, Australia [6].
