Coulomb-nuclear interference effects were investigated in the inelastic scattering of ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ by ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ with excitation of the first $2^{+}$ state in ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$. Measurements were performed at 54 and 60.5 MeV for the elastic and inelastic angular distributions and from 36 to 95 MeV for the excitation functions. The elastic data were analyzed in terms of the optical model. The inelastic results were compared with distorted-wave Born-approximation and coupled channel calculations. The reorientation effect was investigated.
