Application of relativistic distorted-wave method to electron-impact excitation of highly charged Fe XXIV ion embedded in weakly coupled plasmas

摘要: The process of excitation highly charged Fe XXIV ion embedded in weakly coupled plasmas by electron impact is studied, together with the subsequent radiative decay. For target structure, calculation performed using multiconfiguration Dirac-Hartree-Fock method incorporating Debye-Huckel potential for electron-nucleus interaction. Fine-structure levels 1s22p and 1s2s2p configurations transition properties among these are presented over a wide range screening parameters. collision dynamics, distorted-wave relativistic frame adopted to include effect plasma background, which interparticle interactions system described screened type. continuum wave function projectile obtained solving modified Dirac equations. influence strength on cross section, linear polarization, angular distribution x-ray photon emission ...
