Nucleation of (He-3)-B from the A phase - A cosmic-ray effect?When He-3 is liquified and subsequently cooled, it undergoes, at a temperature of approximately 2.0-2.5 mK, a second-order transition into the so-called A phase. On further cooling, a first-order transition occurs, and the liquid passes into the B phase. Supercooling occurs with respect to the second transition, and the problem of nucleation arises. In connection with the experimental interest in studying metastable (He-3)-A down to the lowest temperatures in weak magnetic fields, the understanding of the mechanism of this transition and the feasibility of its inhibition is of some importance. The present investigation is concerned with the possibility that the transition is nucleated by the passage of a cosmic ray through the sample cell.
