Notes:
We study the capillary condensation of liquid 4He films inside narrow slit pores with a density functional model and compare the result to the predictions of the Kelvin equation. Our investigation, in the wetting situation, indicates that pores with sizes up to 100 A(ring) are still too small for the macroscopic thermodynamic arguments used to derive the Kelvin equation to be successful. The discrepancy is tentatively attributed to the use of a slab-density model and bulk parameters in the region of very thin films.
