THE SOLAR-NEUTRINO PROBLEM AND THE RADIOCHEMICAL LITHIUM DETECTOR

The current experimental data on the solar-neutrino problem are review ed. The possibilities offered by the radiochemical lithium detector fo r solving this problem, in particular, for determining the contributio n of medium-energy and boron neutrinos in chlorine and gallium detecto rs, are discussed. A brief description is given of the prototype of th e lithium detector containing a target of 300 kg of metallic lithium, which is presently under construction at the Nuclear Research Institut e of the Russian Academy of Sciences.
