Differential cross-sections for nuclear reactions on Al and Si induced by deuterons at low energy (1–2 MeV)

Recent progress in thin film techniques has made possible the fabrication of stable and pollution-free reference standards. Thin Si3N4 film (thickness 70 nm) and thin Al foil (150 nm) were selected to measure the differential cross-sections of nuclear reactions induced by deuterons, from 1 to 2 MeV. The absence of oxygen and carbon in the standard, as well as the stoichiometry, were checked prior to measurement by RBS. The differential cross-sections of the 27Al(d,p0p1)28Al, 27Al(d,p2p3)28Al, 27Al(d,p5p6)28Al, 27Al(d,p9)28Al, 27Al(d,p10)28Al, 27Al(d,p11)28Al, 27Al(d,p12)28Al, 27Al(d,α0)25Mg and 27Al(d,α2)25Mg reactions for aluminium and 28Si(d,p0)29Si– 29Si(d,p1)30Si, 28Si(d,p1)29Si– 29Si(d,p2)30Si, 28Si(d,p2)29Si, 28Si(d,p3)29Si, 28Si(d,p9p10)29Si reactions for silicon were determined for a detector angle of 150°.
