Observation of the "burst-like growth" regime for the ${}^4$He crystals nucleated in a metastable liquid

Abstract

The "burst-like growth" regime is observed for the ${}^4$He crystals with the growth defects. The observation has confirmed the hypothesis for the same physical mechanisms responsible for the transition of the crystalline facets to the state of abnormally fast growth at high and low temperatures. The relaxation process of the kinetic growth coefficient is found to be similar to the relaxation of the elastic modules of the crystal at the end of the fast growth stage. The kinetic growth coefficients are determined at the stages of fast and slow growth. The crossover from the fast to slow kinetics of crystal facet growth is found to be drastic
