Abstract: The correlation properties are studied of binary mixtures in the critical state of vaporization in external field. The investigations are based on the system of Percus-Yevick integral equations for pair correlation functions $G^{\alpha\beta}(r_1, r_2)$ and the theory of scaling in critical phenomena. Expressions are obtained for pair correlation functions and correlation radius $R_c$, which are analyzed in various extreme cases.
