Elastic scattering of heavy nuclei and nucleus-nucleus potential with repulsive core

The elastic scattering of 16 O + 12 C at various collision energies is discussed in the framework of the optical model with repulsive core nucleus-nucleus potential. The cross sections on backward angles are strongly raised due to repulsive core. It is shown by using the near-side/far-side decomposi...

Zusammenfassung:	The elastic scattering of 16 O + 12 C at various collision energies is discussed in the framework of the optical model with repulsive core nucleus-nucleus potential. The cross sections on backward angles are strongly raised due to repulsive core. It is shown by using the near-side/far-side decomposition method that the near-side component of the scattering amplitude mainly contributes to the elastic scattering cross sections on forward and backward angles. The repulsive core of 16 O + 12 C potential takes place at distances R ≲ 3 fm.
