RADIATION ENHANCEMENT IN A RECOMBINING PLASMA

Gudzenko, L.I., Shelepin,L.A.: 1964, Sov.Phys.Doklady, 10, 147.

The analysis of radiation enhancement in a highly ionized plasma with inversely populated energy levels requires taking into account of the entire set of relaxation times (of the collisional radiative model). The detailed solution of this problem is far from complete; even in a qualitative consideration of the processes accompanying the decay of such plasma, it is convenient to distinguish the following three stages: 1) a strongly-ionized plasma with 'instantaneous' cooled free electron when the lower levels are still almost unpopulated; 2) a substantially-ionized plasma in which 'stationary drainage' has been established, with superpopulated upper levels; 3) a weekly-ionized plasma.
