Notes:
The revised capillarity approximation (RCPA) of McGraw and Reiss [J. Stat. Phys. 20, 385 (1979)] is reexamined using established liquid drop models to evaluate the effects of physical cluster excluded volume on the thermodynamic barrier to nucleation near a critical temperature Tc. A significant heightening of the nucleation barrier is predicted, and the anomalous behavior observed experimentally near Tc is examined within the framework of classical nucleation theory using the RCPA. Definitive methods for experimentally separating this pure nucleation effect from those dependent on slowing down of the post-nucleation completion times for phase separation are described.
