摘要

In a recent journal: the Becker-Doring equation (BDE)was solved numerically for large cluster numbers n, givingthe time-dependent distributions of nuclei far into the growthregion. This provides a unique opportunity of a high-precision verification of the matched asymptotic solution(MAS) of Refs. 2 and 3, which, due to computational chal-lenges of the large-n BDE, was previously tested only formodest R 2R., the critical size. Comparison is especiallyinteresting since large supersaturations S were considered inRef. 1, leading to strong discreteness effects with significantdeviations from the continuous "Zeldovich-Frenkel" limit.
