FULL SECOND-ORDER DISTORTED-WAVE STUDY FOR ELASTIC ELECTRON SCATTERING BY HYDROGEN MOLECULE A. M. Machado and M- T. Lee Instituto de Fisica de Sao Carlos, USP Caixa Postal 369, 13560-970, Sao Carlos-SP, Brazil Departamento de Quimica, UFSCar Caixa Postal 676, 13565-905, Sao Carlos-SP, Brazil A full second-order distorted-wave approximation is applied to study elastic electron-hydrogen molecule collision in the low- and intermediate- incident energy range. The method of continued fractions is used to evaluate the distorted-wave Green's function. Our calculated differential cross sections are in very good agreement with the experimental data.
