Findings

The model accounts for vapor depletion around embryos.

It estimates embryo formation probability during a given time.

Provides a more accurate nucleation rate calculation.

Abstract

A new model to calculate the rate of nucleation is formulated. This model is based on the classical nucleation theory but considers also vapor depletion around the formed embryo. The key characteristic which arises in frames of this theory is the mean time of the embryo formation. On the base of this time the probability to observe the embryo formed during the given time is estimated which allows to construct a simple approximate theory.
