Abstract:

IT IS OBSERVED THAT AT PRESENT THERE ARE NO THEORETICAL METHODS OF CALCULATING CROSS SECTIONS FOR ELECTRONIC EXCITATION OF SMALL MOLECULES BY SLOW ELECTRONS UNLESS THE MOLECULE IS DIATOMIC OR APPROXIMATELY SPHERICAL. A number of general procedure suitable for use with the Hulthens or Kohn Variational Methods and for few-centre molecules are formulated, and a new expansion theor m is derived. It is concluded that the procedure referred to as the Static Centroidal is the most promising of those examined. Author
