Elastic and rotational excitation of the nitrogen molecule by intermediate-energy electrons

摘要: The eikonal amplitude for a fixed molecular orientation is used in the framework of adiabatic approximation to calculate pure elastic excitation (0 ..-->.. 0 and 1 1), rotational 2 3), average cross sections hydrogen molecule its ground electronic vibrational states using electrons as incident projectiles. Both differential integral are reported at electron energies 20--200 eV. For processes, effects target polarization exchange considered, while inelastic processes only effect taken into account. Results obtained compared with those other theoretical experimental workers. It found that comparable intermediate large scattering angles, they depend on initial state J such way remain independent J.
