On the proximity relation between two surface-melted clusters involved in inter-cluster mass transfer

We explore Ow way free particles produced by dissociating "particle-hole pa irs" on a surface-melted cluster can be transferred to a second, nearby sur face-melted cluster. This mass transport is based on an inter-cluster direc t transfer mechanism of the particles. We found that in this particular cas e one cluster may grow at the expense of another, obeying a temporal power law with the exponent 1/2 for the average radius (R similar to t(1/2)). The change from the expected universal power law (R similar to t(1/3)) is a co nsequence of the proximity relation between these two clusters which lead t o enhance the effective transport rates.
