摘要：

We have measured the roughening exponent chi at the interface between a pair of growing Eden clusters. Our numerical results suggest that chi differs from the corresponding exponent for a freely growing interface, and that it depends on the initial geometry of the clusters, which grow into a vacant sector with an angle theta. For theta < 180-degrees we find chi = 1/3, and our results are consistent with chi = 2/3 for theta = 180-degrees and chi = 1 for theta > 180-degrees.
