  We simulate the collision of atomic clusters with a weakly attractive surface
using molecular dynamics in a regime between soft-landing and fragmentation,
where the cluster undergoes large deformation but remains intact. As a function
of incident kinetic energy, we find a transition from adhesion to reflection at
low kinetic energies. We also identify a second adhesive regime at intermediate
kinetic energies, where strong deformation of the cluster leads to an increase
in contact area and adhesive energy.
