The regular periodic intensity bursts recently observed in the expansion of solid 4He into vacuum have anomalies that have been attributed to a transition to some new solid phase induced by excess vacancies. Here it is shown that a small concentration of 3He, from 1% down to 0.1%, added to the 4He solid is sufficient to remove all the anomalies. The origin of the observed anomalies is discussed in the light of these new experiments.

Abstract

The regular periodic intensity bursts recently observed in the expansion of solid 4He into vacuum have anomalies that have been attributed to a transition to some new solid phase induced by excess vacancies. Here it is shown that a small concentration of 3He, from 1% down to 0.1%, added to the 4He solid is sufficient to remove all the anomalies. The origin of the observed anomalies is discussed in the light of these new experiments.
