摘要：

The temperature dependence of the growth coefficient in the angular vicinity of the basal [0001] facet of hcp He-4 crystals has been measured in the temperature range from 0.35 K to 0.45 K. Contrary to theoretical predictions this dependence turned out to be much stronger for vicinal surfaces than for nonvicinal orientations. For vicinal surfaces experimental data can be approximated by both K is-proportional-to T-5 and K is-proportional-to exp [epsilon/T] dependences, where epsilon = 1.9 K.
