Abstract

We present new experimental data for the inclusive (p,xp) and (p,x $α$ $\alpha$ ) reactions on $^{27}$ $^{27}$ Al target. Double-differential cross sections of (p,xp) at energies 7, 22, 30 MeV and (p,x $α$ $\alpha$ ) at energies 22, 30 MeV within the angular range of 30 $^{\circ}$ $^{\circ }$ –135 $^{\circ}$ $^{\circ }$ have been measured for the first time. The data has been analyzed by using the exciton model, along with multistep direct and multistep compound models to evaluate the adequacy of the theoretical models in explaining the measured data. Our calculations indicate that the exciton model captures the general trends and oscillatory structures of the spectra at higher proton energies; however, the agreement between theory and experiment remains qualitative, reflecting the inherent complexity of pre-equilibrium reaction mechanisms.
