Relation between the β and rapidly quenched liquid phases of gallium

From molecular-dynamics simulations, it is demonstrated that (1) a rapidly quenched Ga liquid contains many 1201- and 1311-types atomic bonded pairs and (2) the 1311-type atomic bonded pairs decrease along with a corresponding increase in the 1201 atomic bonded pairs in the crystallization, so that the {β}-type crystal transition occurs from the supercooled Ga liquid on cooling, or from the pure Ga glass on heating.
