Abstract
Crystal growth of3He in restricted and bulk geometries is described. A striking feature is the growth of single crystals inside a metallic power of 0.3 µm mean grain size. Comparison of the intensity of the (1, 1, 0) and (2, 0, 0) Bragg reflections gives a direct estimate of the zero-point motion. No temperature dependence of the Debye- Waller factor is observed.
