  • Resumen
    • Experiments on the electronic excitation of molecules using positron as incident particles have shown much larger cross-sections than in the electron scattering case. The comprehension of these inelastic processes represents a great challenge and only a few studies on electronic excitation of molecules are discussed in the literature. For example, for the C_(6)H_(6) molecule experimental, and theoretical calculations are not in a very advanced state, same for electron scattering case (Benzene represents the simplest aromatic hydrocarbon and a very important chemical compound due to its role as a key precursor in process pharmaceutical). Recent experiments on electronic excitation of C_(6)H_(6) (^(1)B_(1u), and ^(1)E_(1u) electronic states) using electron as an incident particle are available by Kato et al. (J.Chem.Phys. 134 (2011) 134308). Motivated by their experiments, we have investigated the same electronic excitation of C_(6)H_(6) using positron as an incident particle. For the first time, integral cross sections in e^(+) - C_(6)H_(6) (^(1)B_(1u), and ^(1)E_(1u) electronic states) using the scaling Born positron (SBP) approach are reported. In the absence of the experimental data and theoretical developments, comparisons are made with analogous electron scattering.
