Evidence concerning drying behavior of Ne near a Cs surface - art. no. 206103

Using density functional and Monte Carlo methods, we have studied the prope rties of Ne adsorbed on a Cs surface, focusing on the region at and near sa turated vapor pressure (SVP). In the case of Ne/Rb, the experimental data o f Hess, Sabatini, and Chan are consistent with the calculations based on an ab initio fluid-substrate potential, while in the Ne/Cs case there is indi cation that the potential is similar to9% too deep. In that case, the calcu lations yield partial drying behavior consistent with the experimental find ing of depressed fluid density near the surface, above SVP. However, we fin d no evidence of a drying transition, a result consistent with the mean-fie ld calculation of Ebner and Saam.
