摘要
We explore the way free particles produced by dissociating ``particle-hole pairs'' on a surface-melted cluster can be transferred to a second, nearby surface-melted cluster. This mass transport is based on an inter-cluster direct transfer mechanism of the particles. We found that in this particular case one cluster may grow at the expense of another, obeying a temporal power law with the exponent 1/2 for the average radius R = const t^{1/2}. The change from the expected universal power law R = const t^{1/3} is a consequence of the proximity relation between these two clusters which lead to enhance the effective transport rates.
