Popis:	Optical reflectivity of free-standing films in the temperature interval of the smectic phases and above the bulk smectic-nematic transition temperature has been studied. Melting phenomena have been found to be dependent on the film thickness. For thick films, nematic-like droplets and an unstable state over the entire film have been observed above the bulk smectic-nematic transition temperature. These droplets and the unstable state of the film look like the “quasi-smectic” phase predicted by Mirantsev.
