Immediately it can be seen that the potential well for the secondary layer, at 1.0 bar, has a minimum not nearly equal to thermal translational energies at the temperature in question. Therefore, this layer potential could only act to trap the small fraction of low velocity gaseous particles at this temperature. This result is not inconsistent with the density profile predicted in Reference as the secondary layer does not seem to fill as a stand alone region but rather begins to gather particles as the entire inner region fills with increasing pressure. The radial boundaries, predicted here for this secondary layer, are consistent with the result in Reference .
