Electrons are ever present in nature and electron induced reactions in the gaseous or condensed phase or on surfaces initiate and drive the basic physio-chemical processes in many areas of science and technology from industrial plasmas to living tissues. For the successful design and operational modelling of ‘International Thermonuclear Experimental Reactor’ (ITER) and other fusion reactors, electron transport through the plasma is of fundamental importance. The electron impact collision process becomes dominant in different plasmas used in modelling of fusion edge plasmas, chemical vapour deposition, semiconductor chip manufacturing etc.
In the talk the work regarding electron induced collision and attachment of different important technological and industrial molecules will be discussed. The ab-initio R-matrix formalism for the calculations of electron impact scattering cross sections at low energy will be explained. This method is a useful formalism to calculate the electron impact cross section at low energies. In the talk, we will explain different resonance features which were detected by the present theory indicating the probability of anions formation by the electron attachment process and further decay to neutral and negative ion fragments. Previous theoretical results with different experimental verifications will be presented during the seminar. The different future prospects and plan of the work about the electron impact scattering and attachment cross sections will be discussed during the presentation. |
