The results are well fitted by a mass formula in powers of x=N-1/2, where N is the number of particles. The analysis of the mass formula allows for the extraction of the line tension, which turns out to be 0.121 K/Å. Sizes and density profiles of the puddles are also reported.5 p.application/pdfeng(c) The American Physical Society, 2003Heli líquidClústersMètode de MontecarloLiquid heliumClústersMonte Carlo methodinfo:eu-repo/semantics/article515126info:eu-repo/semantics/openAccess
