Nuclear spallation reactions
WebAs the energy of protons incident on a spallation target increases, the number and energy of neutrons produced increase. Figure 8 illustrates this effect Target material … WebPreviously determined nuclear spallation reactions of Fe are recalculated making use of improved total inelastic and partial reaction cross-sections that result in different absolute and relative abundances of the main spallation elements Mn, Cr, V, and Ti.
