Abstract

Snowball is a charged aggregate of helium atoms around an impurity ion in liquid helium. 8Li nuclei as obtained with nuclear reaction ,7Li(d, p)8Li were admitted into liquid helium and the ions were driven by an electric field to surface-barrier detectors. From the variation in number of detected alpha-particles with delay time, half-life of snowballs was obtained as 352 ± 82 ms. The observed long lifetime underlines the view of the experiment that the snowballs constitute a suitable milieu for preserving nuclear polarization throughout the lifetime of core ions 12B produced in the reaction 232Th(14N, 12B).
