Study on incident ion internal structure effect on elastic scattering

Experimental results on elestic scattering of deuterons, 3He and alpha-particles on 12C are subjected to a qualitative analysis. The differential cross sections of the elastic scattering of complex particles with the wave number k approximately 1 Fm-1 and K approximately 1.3 Fm-1 are presented. The interaction parameters of 2H, 3He and 4H with 12C are listed in the table. Factors that can cause variations in the absolute magnitudes of the cross sections depending on the ion used are discussed: 1) the excitation energy and system state structures; 2) the inner structure of a nucleus-target; and 3) the inner structure of an impinging ion. It is concluded that the most substantial effect on the cross sections is exhibited by the impinging ion structure which is primarily manifested through the binding energy
