ABSTRACT: A
semimicroscopic analysis of a set of experimental data of elastic α + 12C scattering was performed at several laboratory energies. The
Woods-Saxon parameters were adjusted to obtain the best χ2 fit to the scattering data. The energy systematics of
the positions of Airy minima was constructed, and it was shown that their
positions depend linearly on the inverse center of mass energy. The parameters
of the model potential have been determined unambiguously. It has been shown
that the energy dependence of the volume integrals satisfies the dispersion
relation and agrees well with the results obtained within a phenomenological
analysis. Also, it has been shown that the found positions of the Airy minima
satisfy the rule of the quadratical dependence of the position of the Airy
minima on the reduced mass of the colliding nuclei.
