GALLEX results from the first 30 solar neutrino runs

ABSTRACT

166We report new GALLEX solar neutrino results from 15 runs covering 406 days (live time) within the exposure period 19 August 1992-13 October 1993 (“GALLEX II”). With counting data considered until 4 January 1994, the new result is [78± 13 (stat.) ± 5 (syst.)] SNU (1σ). It confirms our previous result for the 15 initial runs (‘‘GALLEX I”) of [81 ± 17 (stat.) ±9 (syst.)] SNU. After two years of recording the solar neutrino flux with the GALLEX detector, the combined result from 30 solar runs (GALLEX I + GALLEX II) is [79±10 (stat.) ±6 (syst.)] SNU (1er). In addition, 19 “blank” runs gave the expected null result. GALLEX neutrino experiments are continuing.
