摘要
When an acoustic wave pulse was applied to metastable superfluid He-4 above the melting pressure, a bulk He-4 crystal was nucleated in the superfluid at low temperatures. Overpressure in which the metastable liquid could exist was investigated by changing the acoustic wave power. A larger power pulse could nucleate the crystal in smaller overpressures, which decreased linearly in the acoustic wave power.
