A balanced and comprehensive account is given here of the electron-atom-molecule scattering calculations carried out by the author. The topic is of great interest owing to many-fold relevance e.g. in the planetary and outer space environments. Collisions of electrons with atoms and molecules provide a unique diagnostic probe of the fundamental interactions of atomic-molecular systems and are the basic physical processes that determine the behavior of ionized gases. To understand and to predict quantitatively the behavior of ionized gases found in planetary environments etc, requires...

The present book is in continuation of our sincere efforts towards the applications of electron scattering cross sections (Volume-I), in the modeling of various planetary atmospheres. In this backdrop the present book focuses on important applications of our calculated ionization cross sections in various planetary environments. As a case study, electron ionization for N2 and O2 are calculated and employed to compute the ionization mean fee path and ionizing collision frequencies for the incident electrons in the D and E regions of the Earth's ionosphere. Further in the ionospheres of Mars...

The present volume shows the diverse applicability of our theoretical methodology for carry out cross section calculations ranging from gaseous targets to the solids. The book covers our modest theoretical efforts to carry out calculations on electron interactions with atomic-molecular targets in condensed/solid phase. Presently the inelastic mean free path (IMFP) of incident electrons is calculated as a function of energy for bulk forms of Si, SiO2 and SiO together with Al2O3 by employing atomic/molecular inelastic cross sections derived by our semi-empirical quantum mechanical method. The...
