Abstract:

Detailed calculations of population densities of excited levels in a decaying hydrogen plasma flow predict population inversions within a definite range of plasma parameters. This has been verified experimentally in a rapid expanding plasma where the characteristic time of decay was much shorter than the relaxation time of the ground state. Population inversions have been found for the first transitions of the Paschen and Brackett series. Author
