  We study lead nanodroplets containing 147 to 1415 atoms at temperatures
ranging from the bulk melting point up to the beginning of the evaporation
regime. Molecular dynamics simulation and an embedded atom potential are used.
The structures, total energies, and mobility of atoms in the clusters are
analyzed. We found that the liquid cluster of 147 atoms shows a pronounced
tendency to form non-spherical shapes, and sometimes separates into two
droplets. Bigger clusters disassemble by evaporation of monomers. We also
explore shape oscillations of these nanodroplets using the nuclear liquid drop
model.
