Variational calculations forHe3impurities onHe4droplets

Variational Monte Carlo method is used to calculate ground state properties of ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ 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 ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ impurities. The kinetic energy density of ${}_{}{}^4{}_{}{}^{}\mathrm{He}$ atoms and the energy of the ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ surface states are compared with the results of previous phenomenological calculations.
