H. Vach et al., Structure-dependent evaporation dynamics for the surface scattering of binary Van der Waals clusters, CHEM P LETT, 314(5-6), 1999, pp. 552-557
Molecular dynamics simulations have been performed to simulate the surface
scattering of Ar827Kr110 clusters for two different initial cluster structu
res: one with the krypton dopants localized in the outermost cluster layers
(belt structure) and one with all Kr atoms forming a core in the center of
the mixed cluster (core structure). As for the experimental scattering fro
m a graphite surface, we find that the two cluster species leave the same p
arent cluster with considerably different evaporation temperatures. We show
that these temperatures depend crucially on the initial cluster structure
and that the core configuration leads to significant cage effects. (C) 1999
