Abstract

We have obtained inequality where J is the frequency of homogeneous nucleation, V and are, respectively, volume and average lifetime of the superheated liquid, and is relative statistical error Inequality appears to be a consequence of nucleation homogeneity and stability used at its deduction and taken in the theory as initial and determinant assumption. Calculations with the use of experimental data for the boundaries of the attainable superheating show that inequality is not satisfied. Thus, experimental data can not be considered a proof of the theory fundamentals.
