摘要: Abstract Rotational excitation in the Ar+N 2 system is investigated using P -helicity decoupling approximation. The accuracy of this approximation demonstrated. Opacity functions, elastic and inelastic differential cross sections are computed. results agree reasonably well with those available from molecular beams scattering experiments. energy dependence oscillatory structure discussed. It explained by an interference mechanism very similar nature to that scattering. relative role short- long-range anisotropies, kinematics factors type transition determining shape analyzed some detail.
