Resumen:
A new semi-microscopic functional for studying adsorption of$^4$He on solid surfaces is presented. In this proposal thehelium-helium interaction is screened at small distances by thepair distribution function $g(r)$ and, in addition, thecontribution which plays an important role in the interpretationof the experimental static response function is written in termsof the gradient of $g(r)$. This functional reproduces the usualtest properties. Moreover, a detailed comparison with results ofthe Orsay-Trento density functional is performed.
