Abstract
An alternative theory of homogeneous nucleation based on the theorem on surges has been formulated. This theory gives a steeper temperature dependence of the homogeneous nucleation rate along isobars than that given by the classical Doring?Volmer?Frenkel?Zeldovich?Kagan theory. By the alternative theory, lines of attainable superheat lie much higher than classical ones and are close to the spinodal. Taking into account the dependence of the surface tension on r, i.e., the nucleus radius of curvature, assuming the power dependence of the Tolman length, δ = const/rn, from the theories for different liquids the boundary of attainable superheats moves toward lower temperatures.
