Abstract
We report the complete GNO solar neutrino results for the measuring periods GNOâIII, GNOâII, and GNOâI. The result for GNOâIII (last 15 solar runs) is [54.3â9.3+9.9(stat)±2.3(syst)]SNU(1Ï) or [54.3â9.6+10.2(incl. syst)]SNU (1Ï) with errors combined. The GNO experiment is now terminated after altogether 58 solar exposure runs that were performed between 20 May 1998 and 9 April 2003. The combined result for GNO (I + II + III) is [62.9â5.3+5.5(stat)±2.5(syst)]SNU (1Ï) or [62.9â5.9+6.0]SNU (1Ï) with errors combined in quadrature. Overall, gallium based solar observations at LNGS (first in GALLEX, later in GNO) lasted from 14 May 1991 through 9 April 2003. The joint result from 123 runs in GNO and GALLEX is [69.3±5.5(incl. syst)]SNU (1Ï). The distribution of the individual run results is consistent with the hypothesis of a neutrino flux that is constant in time. Implications from the data in particle- and astrophysics are reiterated.
