  The theory of vapor bubbles nucleation in single-component liquids developed
in [J. Phys. Chem. B 116, 9445 (2012)] for the case of high viscosity (the
(V,/rho,T)- theory) is extended to the case of arbitrary viscosity. For this
purpose, Langevin's approach in the theory of Brownian motion, or Kramers'
model of chemical reactions, is employed. The obtained expression for the
bubbles nucleation rate is valid for arbitrary relations between the kinetic
parameters controlling the nucleation process: viscosity, inertia of a liquid,
the rate of evaporation into a bubble and the rate of heat exchange between the
bubble and ambient liquid. So, the presented theory together with the
(V,/rho,T)- theory gives a complete description of the vapor-bubbles nucleation
kinetics in one-component liquids. Limiting cases with respect to the mentioned
parameters are considered, in particular, the low viscosity limit. It is shown
that the low- and high-viscosity nucleation rates differ from each other
qualitatively and quantitatively. The possibility of application of the theory
to cavitation in superfluid helium-4 is discussed.
