title = "Radioactive core ions of microclusters, {"}snowballs{"} in superfluid helium",
abstract = "Short-lived beta-ray emitters, 12B, sustaining nuclear spin polarization were introduced into superfluid helium. The nuclear polarization of 12B was observed via measurement of beta-ray asymmetry. It was found that the nuclear polarization was preserved throughout the lifetime of 12B (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.",

note = "Funding Information: This study was supported by the Center for Innovative Grouting Materials and Technology (CIGMAT) and the Texas Hurricane Cener for Innovative Technology (THC-IT) at the University of Houston, Texas. Funding for the project (Project No. 10121-4501-01) is provided through the {"}Ultra-Deepwater and Unconventional Natural Gas and Other Petroleum Resources Research and Development Program{"} authorized by the Energy Policy Act of 2005. This program-funded from lease bonuses and royalties paid by industry to produce oil and gas on federal lands-is designed to assess and mitigate risk enhancing the environmental sustainability of oil and gas exploration and production activities. RPSEA is under contract with the U.S. Department of Energy's National Energy Technology Laboratory to administer three areas of research. RPSEA is a 501(c)(3) nonprofit consortium with more than 180 members, including 24 of the nation's premier research universities, five national laboratories, other major research institutions, large and small energy producers and energy consumers. The mission of RPSEA, headquartered in Sugar Land, Texas, is to provide a stewardship role in ensuring the focused research, development and deployment of safe and environmentally responsible technology that can effectively deliver hydrocarbons from domestic resources to the citizens of the United States.
