Measurements of Double Differential Cross Sections for Charged Particle Emission Reactions by 14.1MeV Incident Neutrons

Abstract

The double-differential cross sections for the ²⁷AI (n,x α), ²⁷Al, (n,xp), ^natTi(n,x α), ^natTi(n,xp), ^natZr(n,xp), ¹⁹F(n,x a), ¹⁹F(n,xp) and ^natSi(n,xp) reactions at 14.1-MeV incident neutrons have been measured by using the two-dimensional energy and time-of-flight (E-TOF) charged-particle spectrometer. The measured data were compared with other experimental data, theoretical calculation results with SINCROS- II and evaluated nuclear data. As a result, fairly good agreements were obtained for aluminum and zirconium. However, for titanium, silicon and fluorine, underestimation of evaluated nuclear data was seen in the whole energy range of the spectra.
