Abstract
Contribution of higher order effects to the one-photon exchange approximati on were studied in the first excited state of C-12 by comparing inclusive i nelastic scattering cross sections of electrons and positrons obtained at t he Saclay Linear Accelerator. The data were compared lo a distorted wave Bo rn approximation (DWBA) calculation. The results indicate an effect less th an 2% within 2 sigma, compatible with what was observed in recent elastic s cattering measurements.
