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.
