The 27 Al(n,d)26Mg and 5.6Fe(n,d)55Mn reactions have been studied at 22 Me V incident energy. The 6MV Van de Graafffacility at the National Accelerator Centre, Faure was used for the experimental aspects. An (n, charged parti-cle) spectrometer was used to detect the energy and angle of the outgoing deuterons. The spectrometer allows for accumulation of particle discrim-inated data over an angular range of 800. The intrinsic geometry of the spectrometer limits its ' angular resolution to ' " 50 (FWHM). The spectrom-et er has an energy resolution of' " 0.7MeV(FWHM). A detailed study of the experimental system has been conducted and the proportional counters in particular were extensively investigated. A review of the relevant nuclear models for the target and residual nuclei is presented, together with a theoretical outline of the reaction mechanism for the (n,d) reaction. The distorted waves method approach is used in the analysis of the reaction cross sections. Optical potentials are used t
