An approximate expression is derived for the inelastic K-matrix elements for rotational excitation of molecules by electron impact. This expression incorporates a Born-Oppenheimer separation of the projectile and nuclear coordinates in the continuum wavefunction but allows for different energies in the entrance and exit channels. Hence it is particularly suited to near-threshold collisions. The method is applied to pure rotational excitation of H, by comparing approximate cross sections with… CONTINUE READING
