The Thomas-Fermi method has been applied to the problem of screening due to an electron gas confined to a filament and a coaxial infinite cylinder. Using parameters derived for Pt·2.60, the potential in the region between the filament and cylinder due to a source charge in the filament was evaluated and was found to vary approximately as with an effective screening length about ten times that of metallic platinum. The isotropic form of the screened potential shows the close relationship to screening in three dimensions.
