Phys. Rev. B 63, 184513 (2001) [9 pages]Experimental and theoretical study of the radial density distributions of large 3He dropletsReceived 19 September 2000; published 20 April 2001 The integral cross sections of large 3He droplets and the number of atoms in the corresponding droplets (N̅ =2×103–2×104atoms) have been measured in molecular-beam scattering experiments. The experimental results are in very good agreement with integral cross sections calculated from the radial density distributions predicted from density-functional theory calculations. The experimentally confirmed theoretical 10–90% surface thicknesses vary between 8.0 Å (N̅ =103) and 7.6 Å (N̅ =4×104) and are about 30% larger than calculated for 4He droplets of similar sizes. © 2001 The American Physical Society URL:
