molecule has been investigated in the four-body first Born approximation. Cross sections differential in the scattering angle of the projectile ion have been calculated for various molecular orientations. The calculations account for the interference effects due to the coherent scattering of the particles from the two atomic centers. Total cross sections (integrated over the projectile’s scattering angle and averaged over all the molecular orientations) have also been calculated by a three-body version of the classical trajectory Monte Carlo (CTMC) method based on use of a two-center molecular potential, as well as in a semi-classical quasi-molecular model. The obtained total cross sections are compared with the available experimental data and other theoretical calculations. For impact energies above 40 keV a reasonable agreement has been found between the present theoretical results and the experiment.
