Experimental and theoretical study of the radial density distributions of large ^{3}He droplets
Abstract
The integral cross sections of large ^{3}He droplets and the number of atoms in the corresponding droplets (N¯=2×10^{3}2×10^{4} atoms) have been measured in molecularbeam scattering experiments. The experimental results are in very good agreement with integral cross sections calculated from the radial density distributions predicted from densityfunctional theory calculations. The experimentally confirmed theoretical 1090% surface thicknesses vary between 8.0 Å (N¯=10^{3}) and 7.6 Å (N¯=4×10^{4}) and are about 30% larger than calculated for ^{4}He droplets of similar sizes.
