“…There are many mechanisms to explain this phenomenon (for example, the glory effect [8][9][10] and Regge poles [11][12][13][14][15][16]), which leads to uncertainty in the interpretation of experimental data. The scattering cross sections can also be influenced by the cluster structure of light nuclei, which can lead to the contribution of exchange processes with the transfer of clusters [17][18][19][20][21][22], as well as higher-order processes described by triangular and rectangular diagrams of the dispersion theory [23,24]. In addition to the processes listed above, one must also keep in mind the possible contribution of the mechanism of compound nucleus formation.…”

The angular distributions of the elastic and inelastic scattering of α-particles on 10B nuclei were measured at an energy of 29 MeV (with excitation of the 0.718 MeV (1+) state). The data obtained by us, together with the angular distributions of the elastic scattering measured earlier in a wide range of energies from 24 to 90 MeV, were described using an optical model, the coupled-channel method, and parameterized phase analysis. The optimal parameters of optical potentials were found, and a good description of the experimental data in the specified energy range of α-particles was achieved. By taking into account the contribution of the elastic transfer mechanism of the 6Li cluster, it was possible to correctly reproduce the rise of the cross section at the backward angles in the elastic channel. The value of the quadrupole deformation parameter was extracted from the analysis of inelastic scattering using the coupled-channel method. The geometric parameters of the interaction potentials were determined using parameterized phase analysis. The radii of the 10B nuclei in the high-energy region (30 MeV and above) obtained by PPA are in good agreement with the radii calculated in the framework of the optical model.
