Distribution of Neutrons from The Reaction (p, n) on the Liquid Lead Target in The Accelerator Driven System Reactor

This paper presents results of calculating energy distribution, angular distribution, neutron yield, the double-differential cross-section of the neutron as a proton beam, which produced from the accelerator, spallation on the liquid lead, thus providing the basis for the distribution of the target, calculating fuel ... for the accelerator-driven reactor system reactor. These results have shown that the produced neutron energy spectrum extends from thermal neutrons to fast neutrons, which have concentrated in 1MeV to 3MeV. These neutrons are produced at angles of 0(0) to 10(0) and turn decreased to the larger angles. This shows that neutrons tend to be produced forward in the direction of the incoming protons.
