Abstract: | The diagram of the anomalous state of 4He crystals was determined in the range 0.2–0.45 K. Agreement was obtained with the diagram of “bursteike” growth of a dislocation-free facet. This confirms previous assumption about the common nature of these phenomena. The requirements to the theoretical model of the phenomenon are formulated. The growth rate of the facets in the anomalous state was measured up to supersaturations of ~20 mbar. It was found that the growth rate becomes constant and equal to ~3.5 m/s above ~8 mbar. |
