Abstract : In a supersonic expansion of an ionized gas, the dominant factor in describing the atomic processes is generally the recombination rate constant K sub R. Several models describing the recombination process have been reviewed in some detail. It was found that, depending on the adopted definition, different models will yield different values of K sub R for the same electron temperature and number density. A comparison between experimental and theoretical values of K sub R becomes even more complex since in the majority of the experiments K sub R is determined from the measured rate of disappearance of free electrons. These measurements give the correct 'decay coefficient', but only in certain circumstances will it reduce to the correct value of K sub R. (Author)
