The processes involved in the active media of lasers at the 3p-3s transitions of Nel are considered to be well studied [19, 24]: the population of the upper laser level occurs primarily because of the dissociative recombination of [Ne.sub.2.sup.+] and He[Ne.sup.+] molecular ions.
Apparently, the population of the 3p'[[1/2].sub.0] level of Nel under excitation by heavy particles does not occur through the dissociative recombination of molecular ions.
The main conclusion of [25, 28] is that for neon-containing gas mixtures under pumping by heavy particles, the predominant mechanism for the population of the 3p levels of neon is not associated with the dissociative recombination of [Ne.sub.2.sup.+].
Therefore, the dissociative recombination of argon and krypton molecular ions with electrons is not the basic mechanism of the population of the (n + 1)p levels of atoms nor, correspondingly, the nd levels.
It was shown that the population of the [7.sup.3][S.sub.1] level of the mercury atom occurs through the dissociative recombination of ions but not through stepwise excitation by electrons .
It was shown that the dissociative recombination of molecular ions with electrons is not the basic process underlying the population of the p levels of inert-gas atoms.

A major loss mechanism for nitrogen is called dissociative recombination
. This process starts when a positively charged nitrogen molecule at the top of the atmosphere combines with an electron to produce a pair of free nitrogen atoms.
