Resumo: |
Total Cross Sections (TCS) for various processes resulting from the interaction of electrons with poliatomic molecules are clearly needed due to their relevance in many applications. The present study is part of a complete program for the experimental and theoretical determination of various Cross Sections for electron-polyatomic molecule interaction in progress at DQ - UFSCar. An apparatus based on the linear transmission technique with a retarding field after the collision chamber was built. It was need to undertake experimental determinations of TCS for electrons scattering by several targets in the energy range of 300-1000 eV. The experimental results are shown in comparison with calculations using the complex optical potential and the additivity rule. |
