Measurement of recoil nuclei losses for proton-induced reactions in Al, Si, Mg and Fe at 200 and 500 MeV
Abstract
The recoil losses of product nuclei in proton-induced reactions at 200 and 500 MeV in Al, Si, Mg and Fe targets were measured using carbon catcher foils or stacks of Mylar foils. In all cases, the recoil losses were less than 1% for the target thicknesses used and so in the ongoing systematic study to measure cross sections for proton- and neutron-induced reactions, these losses are not important. For Fe targets irradiated at 200 MeV, the recoil losses in the forward direction for several product nuclei measured in both a carbon catcher foil and a Mylar stack were in good agreement. From the recoil losses, the mean forward recoil ranges for several product nuclei were calculated.
