On the Time-Dependent Structure of the Currents in Non-Steady-State Nucleation Kinetics

Using numerical integration, we recently studied the multistate kinetics for non‐steady‐state nucleation in supersaturated water vapor. For cluster sizes $i$ less than the critical size $\mathrm{i*(i\hspace{0.17em}<\hspace{0.17em}i*)}$ , we noted a consistent “overshoot” of the currents $I_i$ from the steady‐state current $I$ . The maximum of $I_i$ is greater in magnitude and is reached at an earlier time $t_i$ as we examine progressively smaller clusters. In this paper, we will present a theoretical argument for the feature of the maximums in the currents.
