two factors always leads to the deceleration of growth with the increase of bubble size.

From Eqs. (\[R\_s-R\_c-Henry\]) and (\[Strong-Zeta-Henry\]) it can be seen that $R_\sigma \gg R_c$. Using this inequality, Eq. (\[Growth-Rate-Henry\]) and boundary condition (\[2Rc\]), we have that the growth rate of the bubble radius in its dependence on this radius has to reach the maximum value achieved at certain bubble radius $R_m$ from the interval $2 R_c \leq R \leq R_\sigma$. Thus it is natural to consider the growth in the following interval of sizes $$\label{1-st}
2 R_c \leq R \leq R_m$$ as a first stage of bubble evolution, where the determining factor is the increase of the driving force of the growth. At this stage bubble growth goes with the increasing in time rate, reaching its maximum at $R_m$.

In order to obtain $R_m$ we will consider the rate of bubble growth as a function of its radius and differentiate both parts of Eq. (\[Growth-Rate-Henry\]) with respect to $R$: $$\label{d-Growth-Rate-Henry}
\frac{d \dot{R}}{dR} = D s \zeta \frac{R_c \left(R_c + R_\sigma \right) - \left(R - R_c \right)^2}{R^2 \left(R + R_\sigma \right)^2}\; .$$ The quantity $R_m$ is defined by the extremal condition $$\label{Extremum}
\left. \frac{d \dot{R}}{dR} \right|_{R =
