  In this paper, we present new experimental data measured at E$_{p}$=29.9 MeV
for the inclusive reactions (p,xp) and (p,x$\alpha$) on nucleus $^{56}$Fe. We
investigate the adequacy of the theoretical models in explaining the measured
experimental data and we determine the contributions of multi-step direct and
multi-step compound processes in the formation of the cross-sections. We show
that the traditional frameworks are valid for the description of the new
experimental data and our measurements are in agreement with the previous
measurements for the (p,xp) and (p,x$\alpha$) reactions on the $^{54}$Fe
nucleus. The only exception is within the energy region of E$_{p}$=15 and 25
MeV for both reactions, where the cross-section for the $^{56}$Fe nucleus is
smaller than the cross-section for the $^{54}$Fe nucleus.
