Double-differential cross section for single ionization of Fullerene by proton projectile

We calculate 3DW-EIS (3 body distorted wave - Eikonal initial state) doubly differential cross sections (DDCS) for single ionization of the C₆₀ fullerene by 75 KeV proton impact. The DDCS is differential in the ejected electron energy and the projectile scattering angle and integrated over the ejected electron angles. The purpose of our study is to look for resonances in outer shell ionization of fullerene and to investigate the importance of the interaction between the scattered proton with ejected electron on the DDCS resonance scattering as a function of ejected electron energy.
