摘要：

We report the first GNO solar neutrino results for the measuring period GNO I, solar exposure time May 20, 1998 till January 12, 2000. In the present analysis, counting results for solar runs SR1-SR19 were used till April 4, 2000, With counting completed for all but the last 3 runs (SR17-SR19), the GNO I result is [65.8 +/- (10.2)(9.6) (stat.) +/- (3.4)(3.6) (syst.)] SNU (1 sigma) or [65.8 +/- (10.7)(10.2) (incl. syst.)] SNU (1 sigma) with errors combined. This may be compared to the result for Gallex (I-IV), which is [77.5 +/- (7.6)(7.8) (incl. syst.)] SNU (1 sigma). A combined result from both GNO I and Gallex (I-IV) tugether is [74.1 +/- (6.7)(6.8) (incl. syst.)] SNU (1 sigma). (C) 2000 Elsevier Science B.V. All rights reserved.
