Electron Impact Excitation Cross Sections of Xenon for Optical Plasma Diagnostic
Abstract
In this project the researcher had taken up the calculation of xenon apparent emission-excitation cross sections for emission lines that have diagnostic value in the analysis of Xe-propelled electric thruster plasmas. Following conclusions were made from the study: The RDW method has been shown to be applicable to transitions between excited states. Since the excitation energy of these transitions is relatively small, first-order theories are valid at lower energies than for excitations from the ground states. The accuracy of the cross section depends crucially on the accuracy of the oscillator strengths obtained from the target wave functions. The use of a relativistic formalism "j-j coupling" clearly explains the huge variation in the magnitudes of these cross sections. The objectives of the project have been achieved and the aimed metastable excitation cross section results of xenon were obtained that are required for the CRM model of Dressler and co-workers and these are being tested and new plasma modeling results are under calculation.
