Electron impact fine structure excitation cross sections of Xe$^{\mathrm{+}}$

Xenon is an ideal and preferred propellant for Hall thrusters......~and ion thrusters. The observed emitted spectra from xenon thruster plasma show also lines from Xe$^{\mathrm{+}}$ [1].$^{\mathrm{\thinspace }}$For the diagnostics of such plasma a collisional-radiative (CR) model is required which involve the dominant process of electron impact excitation (EIE). There are no experimental and theoretical results available for EIE of Xe$^{\mathrm{+}}$. We report detailed EIE results of Xe$^{\mathrm{+}}$ using our fully relativistic distorted wave theory [2] from its ground 5$p^{\mathrm{5}} (J=$3/2) state to the fine structure excited states of 5$p^{\mathrm{4}}$6$s$, \quad 5$p^{\mathrm{4}}$6$p$, \quad 5$p^{\mathrm{4}}$7$s$, \quad 5$p^{\mathrm{4}}$7$p$, \quad 5$p^{\mathrm{4}}$5$d $and \quad 5$p^{\mathrm{4}}$6$d $configurations.
