Solar neutrino mysteries perists
Neutrinos emerge from a variety of reactions between atomic nuclei. As the physics of stars--and particularly the sun--is made up of chains of such reactions, scientists wishing to observe how those reactions proceed have chosen to monitor the flux of neutrinos coming from the sun.
It isn't easy. Neutrinos are the most elusive particles known to physics. From 1971 until last year, the world had only one neutrino observatory, a tank of drycleaning fluid deep in the Homestake mine at Lead, S.D., operated under the direction of Raymond Davis of the University of Pennsylvania. That experiment finds, on the average, about ...
