Abstract—An experimental method providing information about the interaction of electrons with excited CO
molecules at high vibrational levels is proposed and justified theoretically. The suggested experimental scheme
is based on the use of two successive discharge pulses under the conditions prevailing in an electroionization
CO laser. The first pulse should ensure a sufficiently high energy input in order for a nonequilibrium vibrational
distribution function to form. The second pulse serves to study the effect of the electric current on the vibra-
tional distribution function of excited molecules at high vibrational levels. The theoretical analysis is based on
the simultaneous solution of the Boltzmann equation for the electron energy distribution function and the
vibrational kinetic equations realistically describing the multiquantum vibrational–vibrational exchange pro-
cesses. The calculated results show that the sensitivity of the proposed measurement technique promises to be
high. © 2002 MAIK “Nauka/Interperiodica”.
