Uniform Description of Core and Sheath of a Plasma Column

tion through the limitation of the single particle partition function. For temperatures low enough, so that the higher terms in the partition function do not contribute this effect is of course negligible. As it becomes important with increasing temperatures the limitation is determined by e2/r0 and not by e2/D as suggested in Ref. 9 . The above formalism requires extension where the neutral-neural interactions are important. This is the case for the interpretation of the surprising results found from experiments under extreme pressures 14.
