Abstract : The field around the probe in a monoenergetic plasma depends upon the probe radius (made dimensionless with a Debye length), the probe potential and the ratio of the energies of the repelled and the attracted charge carriers. The present report investigates conditions where some of these parameters become either very large or very small. The investigations round out the results of a former report, where only finite values of these parameters were considered. To obtain the desired limiting behavior formal limiting processes are carried out in the differential equation that governs the field around the probe. This method is by no means new, but the variety of examples that occur in the present problem might be rather instructive. For some of the limiting processes numerical results have been included.
