A radiochemical ⁷¹Ga-⁷¹Ge experiment to determine the primary flux of neutrinos from the Sun began measurements of the solar neutrino flux at the Baksan Neutrino Observatory in 1990. The number of ⁷¹Ge atoms extracted from 30 tons of gallium in 1990 and from 57 tons of gallium in 1991 was measured in twelve runs during the period of January 1990 to December 1991. The combined 1990 and 1991 data sets give a value of 58 + 17/-24 (stat) ± 14 (syst) SNU. This is to be compared with 132 SNU predicted by the Standard Solar Model.
