Lithium versus chlorine: For the solution of the solar neutrino problem

Abstract

It is shown that the comparison of the results of the chlorine and lithium detectors can give valuable information for the solution of the solar neutrino problem. A brief description is presented of the prototype of the lithium detector with 300 kg of metal lithium and of the progress in the counting of 7 Be with high efficiency by a cryogenic μ-calorimeter. © 1997 Published by Elsevier Science B.V.
