• Charged pions
• Second-order Eikonal model
• Phase shifts
• Elastic scattering
• pi(+)+C-12
• pi(-)+C-12
• p=995 MeV/c

We present the closed expression for the eikonal phase shifts, including up to the second-order corrections, which has been applied to elastic scatterings of the pi(+)+C-12 systems pi(-)+C-12 and the p = 995 MeV/c. The calculated angular distributions, taking into account the first- and the second-order eikonal phase shifts, show extraordinarily good agreement with the observed data. We also investigate how angular distributions can be influenced by the effective potentials.
