In recent years the whole area of high-energy excitations in solids has flourished well, both experimentally and theoretically. Their spectroscopy and theoretical understanding have important implications for the knowledge of the structure and properties of materials, both in the bulk and near the surface. The theory used in the present work relates to the origin of Non-diagram X-ray spectra in various excitation processes where a deep, as well as the surface electron, is excited. By extending the Bohm-Pines Hamiltonian and utilizing many-body theory, the specific contributions of intrinsic as well as extrinsic "Plasmon-coupling" processes have been obtained theoretically in terms of "Non-diagram parent diagram X-ray line yield ratios" for the high energy plasmon satellite profiles in the X-ray line spectra of 2P main line in compounds of Scandium and Titanium. It has been shown that the high energy X-ray satellite line shapes of Scandium and Titanium compounds observed by de Boer et al. are due to the Plasmon Oscillations. The theoretically calculated results have been probed by comparing them to the relative satellite yields obtained by de Boer et al. and are found to agree well with their experimentally observed values than their calculated values.

In recent years the whole area of high energy excitations in solid has flourished well, both experimentally and theoretically. Their spectroscopy and theoretical understanding have important implications for the knowledge of the structure and properties of materials, both in bulk and near the surface. The theory used in the present work, relates to origin of Non-diagram X-ray spectra in various excitation processes where a deep as well as the surface electron is excited. The specific contributions of the intrinsic as well as the extrinsic ‘Plasmon-coupling’ processes have been obtained theoretically in terms of “Non-diagram-to-parent-diagram X-ray line yield ratios” for the high energy plasmon satellite profiles in the X-ray line spectra of Kα L(0) main lines in Calcium (Ca) and Cobalt (Co) by extending the Bohm-Pines Hamiltonian and using many body theory. It has been shown that the high-energy X-ray satellite line shapes of Calcium (Ca) and Cobalt (Co) observed by Mauron and Douss are due to the Plasmon Oscillations. The theoretically calculated results have been probed by comparing to the relative satellite yields obtained by Mauron and Dousse and are found to agree well with their experimentally observed values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
