Query: Variational Calculations for $^3$He Impurities on $^4$He Droplets   Variational Monte Carlo method is used to calculate ground state properties
of $^4$He droplets, containing 70, 112, 168, 240, 330, and 728 particles. The
resulting particle and kinetic energy densities are used as an input in the
Feynman-Lekner theory for $^3$He impurities. The kinetic energy density of
$^4$He atoms and the energy of the $^3$He surface states are compared with the
results of previous phenomenological calculations.
