ABSTRACT
The possibilities are examined of detecting solar neutrinos by means of the low threshold reaction Ga71(v, e−)Ge71, which can be efficiently employed for recording neutrinos from the H1(p,e+ v)H2 and Be7(e−, v)Li7 reactions. The merits of the radiochemical method based on this reaction are compared with those of other reactions. The cross section for absorption of solar neutrinos by the Ga71 nucleus and the magnitude of the effects on the earth due to neutrinos from various reactions occurring in the interior of the sun are presented. It is pointed out that transitions to the excited states of the Ge71 nucleus may be important for neutrino absorption.
