 note = {P(論文), Ice crystals were grown in free fall by using a large cloud chamber of height 6.5m. Nucleation was carried out by introducing a piece of dry ice in a supercooled cloud produced in the chamber. Ice crystals fell in a supercooled cloud and were collected at the bottom of the chamber. Circular disc crystals grew at temperatures above -1℃. Their size was about 50μm in diameter and about 5μm in thickness. At temperatures about -2℃, hexagonal plates with a lunar pattern grew. It was observed that these patterns were formed by the step growth on basal faces. Circular disc crystals with {(112)^^^-0} crystal faces were observed. It was estimated that these {(112)^^^-0} crystal faces appeared during the growth process from circular discs to hexagonal plates. They disappeared because of their slow growth rate, after forming small hollows on their faces.},
