Abstract. In this study, the diffraction model is employed to study the cluster stripping nuclear reaction on the basis of the Regge-pole method. A formula for the angular distribution is derived. The angular distribution spectra for the cluster stripping nuclear reactions 40Ca(3He,p)42Sc, 40Ca(t, p)42Ca and 54Fe(t, p)56Fe at various energies have been well reproduced with projectile energies varying between 10 MeV and 15 MeV. The predicted theoretical results for the cluster stripping reactions 40Ca(3He,p)42Sc with 10 MeV, 12 MeV and 15 MeV incident 3He; 40Ca(t, p)42Ca with 10.1 MeV incident triton; and 54Fe(t, p)56Fe with 12 MeV incident triton were compared with the experimental data and good agreement was observed. Also a comparison between the diffraction model prediction of the angular distribution values for the cluster stripping reaction 40Ca(3He,p)42Sc at energy 12 MeV of 3He and that of the distorted-wave Born approximation (DWBA) is implemented and a satisfactory agreement between the two methods has been attained.
