We have simulated the growth of the Eden collision interface produced
by the collision of two independent rough growth surfaces made by the
Eden process and measured the cluster size s and the number of the clu
sters n(s) of the collision interface. Here, we have assumed the scali
ng form of s and n(s) as n(s) similar to N(gamma)f(s/N-epsilon), where
N = Sigma s . n(s). We have obtained good scaling. Furthermore, we ha
ve also considered the scaling relation 2 epsilon + gamma = 1.
