TL;DR: The first GNO solar neutrino results for the measuring period GNO I, solar exposure time May 20, 1998 till January 12, 2000 were reported in this article, where counting results for solar runs SR1-SR19 were used till April 4, 2000.

TL;DR: In this paper, the authors measured the rate of production of 71Ge from 71Ga by solar neutrinos and found an average value of 83 + 19 (stat) ± 8 (syst) SNU (1σ), which is consistent with the full pp neutrino flux expected according to the standard solar model.

TL;DR: The radiochemical GALLEX experiment has been measuring the solar neutrino flux since May 1991 and has performed an investigation with two intense 51Crneutrino sources (> 60 PBq) that were produced in the Siloe nuclear reactor and used at the Gran Sasso National Laboratory, one between June and October 1994, and the second between October 95 and February 96.

TL;DR: The GALLEX result of 83 ± 19 (stat.) ± 8 (syst.) SNU is two standard deviations below the predictions of stellar model calculations (124-132 SNU) as discussed by the authors.

TL;DR: The first period of data taking in the GALLEX solar neutrino experiment has been completed and the final result from the 15 runs of this periodpis (81±17 [ stat.]±9 [ syst.]) SNU (1 σ ) as discussed by the authors.
