摘要：

The experimentally obtained dependence on pressure P of the reduced tension E of the electric field, E/N (N is the gas concentration), in the positive column of the glow discharge in neon at 77 K and pressure 20-200 Pa is simulated. The discharge plasma is described by the model in the diffusion-drift approximation. As a result of modeling, the chemi-ionization rate of metastable neon atoms at 77 K is obtained to be 0.64 x 10(-9) cm(3) s(-1). It is found that, with increasing pressure, the effect of the rate of processes with the participation of metastable atoms on the relative accuracy of modeling the dependence E/N on P increases.
