Relative intensity I_<4686>/I_<5876> of the He II line (4686 A) to the triplet line of He I (5876 A) is calculated as a function of the density ratio n (He^<++>)/n (He^+) (or the electron temperature) for a He plasma, whose loss is dominated by axial diffusion rather than volume recombination, under the condition of the electron density n_e∿10^<14>-10^<15>cm^<-3>, the electron temperature kT_e∿2.5-11eV and the ion temperature kT_i∿5-40eV. A collisional-radiative model is used in the calculation of the coefficients of the ionization and recombination processes between He I, He II and He III, where the effect of partial trapping of resonance radiations is taken into account. The calculated result is applied to a magnetically confined plasma of a quasi-steady MPD (magneto-plasma-dynamic) arcjet.
