Query: Comment on ``Jellium model of metallic nanocohesion''   In a recent letter Stafford, Baeriswyl and Burki have provided a simple model
for the elastic force in metallic constrictions of nanometer size. By employing
a semiclassical Weyl expansion for the density of states of transverse modes,
we show that for any smooth cross section, there is a universal contribution (4
epsilon_F)/(9 lambda_F) to the average force which is absent in the presence of
a hole.
