Abstract : The refractive index n1 and the thickness d of the transition layer quasi-liquid layer on the surface of an ice crystal at temperatures just below the melting point 0°C were measured in equilibrium, using an in-situ method of ellipsometry. The transition layers were observed at temperatures above -2 and -4°C for {0001}- and {10MATH0}- faces, respectively, and n1 was 1.330 for both faces, which is very close to the refractive index of bulk water at 0°C nw = 1.333. Combined with the observational results about the ice crystal shapes near the melting point, it was expected that the interface structure between transition layer and ice on the {10MATH0}- face changes from smooth to rough at -2°C.
