THE APPEARANCE OR DISAPPEARANCE OF FACETS AT THE SURFACE OF A CRYSTAL, OR ROUGH TRANSITION, IS A PHASE TRANSITION OF THE KOSTERLITZ-THOULESS TYPE. THE TEST STUDY DEALS WITH HELIUM 4 CRYSTALS, UNDER 25 ATMOSPHERES, INITIALLY OF ROUND SHAPE, AND SHOWS BY COOLING, THREE ROUGH TRANSITIONS (APPEARANCE OF FACETS AT THE SURFACE), AT 1.28, 1 AND 0.35 K. JUSTIFICATION OF THE SELECTION OF HELIUM 4 AS A STUDY MATERIAL (HIGH THERMAL CONDUCTIVITY, HENCE GOOD TEMPERATURE HOMOGENEITY AND RAPID EQUILIBRATION). THEORY OF THE GRWHO RA UFS V.
