Plasma conditions for generating a population inversion between the ground
and first excited states in a recombining hydrogen plasma have been
investigated on the basis of the CR model. Population inversion can be expected
when three-body recombination plays a dominant role; the required regions of
electron density and temperature are specified. It is shown that upper
bounds exists for the ground-state population density at given electron
density and temperature. Larger inversion densities can be obtained between
the ground and first excited states than between excited levels.
Numerical results are presented.
