The effect of a parity-dependent central potential and a spin-orbit potential on the angular distributions of analyzing powers and cross sections in heavy ion scattering is investigated. The cross section data of ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$ + ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ + ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, and ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$ + ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$ scattering are analyzed and it is predicted that a characteristic oscillation appears in the angular distributions of analyzing powers, especially at back angles, for heavy ion scattering with identical cores.
