| Zusammenfassung: |
The nonwetting of liquid 4He on Cs below = 2 K is now well established. However, there exist discrepancies between the measured contact angles and hysteresis at the phase transition of various groups. These are attributed to the influence of the underlying Cs surface. Little is known, however, about the morphology of this surface. There is also a lack of information concerning the dewetting dynamics of metastable 4He films and the dewetting process of 4He drops on this weak binding surface Cs. We present results showing the influence of surface properties on the dewetting behaviour of these metastable films and discuss the scenario of dewetting of a macroscopic helium drop.
