Sažetak

Possible stable structures and energetics of palladium clusters, Pdn (n = 2–40), have been investigated
by performing molecular-dynamics simulations based on a Lennard-Jones type pairpotential.
To determine a preferable growth mechanism, the growing pattern of Pdn clusters
was analyzed via rearrangement collisions and the simple quenching technique. Main observed
results are that palladium clusters prefer three-dimensional structures and spherical clusters of
medium size appear to have five-fold symmetry. The results are compared with those from previous
theoretical studies.
