New study of spallation reactions (Be + p) and (Sn + p) at 1.2 GeV per nucleon

Abstract

The aim of this study is to calculate neutron multiplicity per incident proton in the collision of 1.2 GeV energetic proton beams with Beryllium and Tin. These targets had been estimated using INCL4/ABLA physics models. The results of our Monte Carlo optimization study using MCNP.6 code gives several findings: the neutrons levels produced by Beryllium (Be) and Tin (Sn) respectively are 2.7n/p and 13 n/p; the neutron current scatter varies by the incident angles of the proton beam and the variation of the neutron intensity in the targets. This paper summarizes principles of the method that determine the spectrum of high-energy neutrons, which improve with precision neutron flux, current, and calculation yield.
