Contribution of the Variable Phase Method to the Frame Transformation Theory of Rotational Excitation of Molecules by Electron Impact

Abstract

The extension of electron atom scattering techniques to molecular targets must face two major complications:
  1. (1)

    the strong anisotropy of electrostatic interactions

     
  2. (2)

    the dynamical coupling with the nuclear motion.

     
The exact description by standard collisional techniques — a close coupling (CC) type one-center expansion with a large number of closely spaced states of the molecule, and a large number of partial waves to describe the motion of the colliding electron in the laboratory frame (LF) anisotropic molecular field- becomes a prohibitive task as soon as one wants to go beyond the rotational excitation of the lighter homonuclear diatomics.l
