ASTROPHYSICS:
New Headaches for U.S.-Russia Experiment
Vladimir Pokrovsky and Andrey Allakhverdov
MOSCOW--A tug-of-war over 60 tons of precious gallium is threatening to undermine a major neutrino experiment. This week, officials at the Baksan Neutrino Observatory in Prielbrusye are asking a court to stop a government order to sell off some of the liquid metal, which serves as an underground detector. It's the latest round in a long-running battle over the fate of the material, which has a market value of $500 to $600 per kilogram.
