Abstract

Novel methods were applied successfully to trap ions and to freeze out their nuclear spin polarization inside aggregates of helium atoms, "snowballs" in superfluid helium. Polarized beta-ray emitting ¹²B ions (T_1/2 = 20.4 ms) were injected into superfluid helium and snowballs were created around the impurity ions. Beta rays were detected to locate snowballs and the beta-ray asymmetry was measured to obtain the nuclear polarization of decaying ¹²B. The comparison with the initial value of ¹²B polarization produces that no relaxation in polarization was observed throughout lifetime of ¹²B.
