Universal surface scaling function for critical adsorption

We present an accurate determination of the one- and two-phase universal su rface scaling function which describes critical adsorption at noncritical i nterfaces of critical binary liquid mixtures in the strong surface field li mit. The 95% confidence levels for this function are also determined. This function quantitatively describes ellipsometric critical adsorption data fo r three upper critical and one lower critical binary liquid mixtures. [S106 3-651X(99)04705-4].
