The melting of isolated neutral tin cluster distributions with mean
sizes of about 500 atoms has been investigated in a molecular beam
experiment by calorimetrically measuring the clusters' formation
energies as a function of their internal temperature. For this purpose
the possibility to adjust the temperature of the clusters' internal
degrees of freedom by means of the temperature of the cluster source's
nozzle was exploited. The melting point of the investigated tin clusters
was found to be lowered by 125 K and the latent heat of fusion per
atom is reduced by 35% compared to bulk tin. The melting behavior
of the isolated tin clusters is discussed with respect to the occurrence
of surface premelting.
