Double-differential (n,xp) and (n,x{alpha}) cross-section ratio measurements are performed at the 7-MV Van de Graaff accelerator laboratory for neutron energies between 2.0 and 15.6 MeV. The following reaction rate ratios are measured: {sup 58}Ni(n,x{alpha}) to {sup 27}(n,{alpha}), {sup 58}Ni(n,x{alpha}) to {sup 58}Ni(n,p), {sup 63}Cu(n,xp) to {sup 27}Al(n,{alpha}), and {sup 63}Cu(n,xp) to {sup 58}Ni(n,p). Protons or alphas are detected by {Delta}E-{Delta}E-E telescopes under 14, 51, 79, 109, and 141 degrees. The energy spectrum of the emitted particles and the angular yield distribution are measured. First, the measurements provide double-differential cross-section data for {sup 27}Al(n,{alpha}) and {sup 58}Ni(n,p) by normalization to the known total yield reference cross-section values. Subsequently, the reaction rate ratios of {sup 58}Ni(n,x{alpha}) and {sup 63}Cu(n,xp) to {sup 27}Al(n,{alpha}) or {sup 58}Ni(n,p) provide double-differential cross sections of {sup 58}Ni(n,x{alpha}) and {sup 63}Cu(n,xp) in b/(MeV {center_dot} sr). The measured double-differential cross section data, the particle energy spectra, the angular distributions, and the total yield cross-section data are compared with measured data from literature and with nuclear reaction model calculations performed at the Institute for Reference Materials and Measurements with the computer codes STAPRE-H and EXIFON.
