The solar neutrino problem and the radiochemical lithium detector

Abstract

The current experimental data on the solar-neutrino problem are reviewed. The possibilities offered by the radiochemical lithium detector for solving this problem, in particular, for determining the contribution of medium-energy and boronneutrinos in chlorine and gallium detectors, are discussed. A brief description is given of the prototype of the lithium detector containing a target of 300 kg of metallic lithium, which is presently under construction at the Nuclear Research Institute of the Russian Academy of Sciences.
