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

摘要

Recent progress in thin film techniques has made possible the fabrication of stable and pollution-free reference standards. Thin Si_3N_4 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 ~(27)Al(d,popi)~(28)Al, ~(27)Al(d,p2p3)~(28)Al, ~(27)Al(d,p_5p_6)~(28)Al, ~(27)Al(d,p_9)~(28)Al, ~(27)Al(d,pio)~(28)Al, ~(27)Al(d,p_(11))~(28)Al, ~(27)Al(d,p]2)~(28)Al, ~(27)Al(d,a0)~(25)Mg and ~(27)Al(d,a2)~(25)Mg reactions for aluminium and 28Si(d,p0)29Si-~(29)Si(d,p_1)~(30)Si, ~(28)Si(d,p_1)~(29)Si- ~(29)Si(d,p_2)~(30)Si, ~(28)Si(d,p_2)~(29)Si, ~(28)Si(d,p_3)~(29)Si, ~(28)Si(d,p_9p_(10))~(29)Si reactions for silicon were determined for a detector angle of 150°.
