Energy of the Conduction Band in Near Critical Point Fluids
Figure 2
plotted as a function of reduced number density . Minimum energy of the conduction band, obtained from (3), plotted as a function of reduced number density , where is the critical density, for Kr [2, 7, 10, 12], Xe [2, 8, 12], CH4 [1, 2], and C2H6 [1, 2] at noncritical temperatures (solid markers) and on an isotherm near the critical temperature (open markers). The average error in the Kr and Xe measurements presented here is approximately 0.02 eV [2]. The error bars for the CH4 and C2H6 measurements are shown. The lines in these figures are calculated using the local Wigner-Seitz model (see text for discussion).
