The diffractive structure of experimental differential cross sections of elastic scattering of 23 light nuclei with masses 3 ≤ A ≤ 20 on C was studied for collision energies from 1 up to 200 MeV/nucleon and transferred momenta up to q < 3–4 fm−1. A common assumption of a diffractive nature of the interaction in these conditions is confirmed by a quantitative analysis of specific features of the differential cross section such as positions of maxima and minima. Their energy evolution as well as that of the corresponding diffraction radius are parameterized with smooth functions. The presented approximation provides an adequate description of experimental data and has a certain predictive power. The observed correlations between the diffraction radius parameters and the structure features of nuclei can be used as a source of information about internal nuclear structure and also as a base for a consistency check between different experimental studies.
