SCATTERING OF ELECTRONS FROM ATOMIC AND MOLECULAR SYSTEMS

Abstract

The work reported in this thesis is the result of author's attempt to investigate and obtain an understanding of the collisions of charged particles with atomic and molecular systems. The first part of the thesis is concerned with the scattering of electrons by atoms using quantal methods. Also collisions between atomic and molecular systems resulting in either excitation or ionization have been investigated quantum mechanically. In the second part of the thesis, a classical approach has been followed for the study of 4 inelastic collisions of electrons with atoms and ions. The first chapter gives a review of the various quantal and classical theories of scattering, and the experimental data. In the second chapter we make use of the Glauber theory to study the electron—lithium elastic and inelastic scattering. It is observed that the Glauber theory gives a better • agreement with the data than any other theory.
