Cross Sections and Rate Coefficients for the Interaction of a Monoenergetic Neutral Lithium Beam with a Maxwellian Plasma

摘要

Cross sections and rate coefficients for the interaction of a monoenergetic neutral lithium beam with a Maxwellian plasma are presented. Experimentally determined cross sections from the literature are used for the ionization of lithium atoms by electron impact and by charge exchange on protons as well as for the excitation of the Li(2s-2p) line by electrons. The analytical expressions of Cryzinski are employed to compute the cross sections for the ionization of lithium by ions and for the excitation of the Li(2-2p) line by ions. The calculations are done for electron and proton temperatures in the range 10 eV to 10 keV with the lithium beam energy being varied as a parameter between 4 and 100 keV.
