Abstract

Angular distributions for elastic scattering of alpha particles on

^{27}

Al,

^{28}

Si,

^{32}

S, Ti and

^{59}

Co nuclei have been measured in the angular range from about 20

^{\circ}

to 179

^{\circ}

(LAB). The experimental data were fitted with the optical model in full angular range. Many sets of four-parameter potentials, describing the elastic scattering, were found with the depths of the real part ranging from 40 to 450 MeV. A new discrete ambiguity in the optical model namely in
