抄録

Short-lived beta-ray emitters, 12 B, sustaining nuclear spin polarization were introduced into superfluid helium. The nuclear polarization of 12 B was observed via measurement of beta-ray asymmetry. It was found that the nuclear polarization was preserved throughout the lifetime of 12 B (20.3 ms). This suggests that the "snowball", an aggregation of helium atoms produced around an alien ion, constitutes a suitable milieu for freezing-cut the nuclear spin of the core ion and that most likely the solidification takes place at the interior of the aggregation.
