摘要：

Water adsorption on polished (111) surfaces of BaF2 and CaF2 was studied at room temperature under ultrahigh vacuum conditions by optical second-harmonic generation. Above 10(4) langmuirs, thc total second-harmonic yield decreases with increasing exposure. The azimuthal anisotropy is influenced differently on each substrate. Below 10(4) langmuirs the 3m symmetry of the crystal surface is preserved in both cases, but more pronounced for CaF2. At high doses the symmetry remains for BaF2, but vanishes for CaF2. The results point to pseudomorphous epitaxial growth of water on BaF2 but not on CaF2.
