Abstract

We investigate theoretically the linear polarization of the Helium-like resonance line 1s2p 1P1 1s2 1S0 emitted from C4+ ions using a steady-state collisional-radiative model, taking into account both the excitation from the ground level 1s2 1S0 and the metastable level 1s2s 1S0 in the population of the 1s2p 1P1 upper level of the resonance line. We analyze the behavior of the linear polarization of the resonance line with respect to the electron density in a wide range varying from 1011 to 1017 cm-3 and for three specific energies of the electron beam. Our results show that when the electron density is sufficiently high, the excitation 1s2s 1S0  1s2p 1P1 provide a significant contribution to the population rate of 1s2p 1P1 level which lead to an important depolarization of the resonance line.
