Abstract
We 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 19 94, the new result is [78 +/- 13 (stat.) +/- 5 (syst.)] SNU (1 sigma). It confirms our previous result for the 15 initial runs (''GALLEX I'' ) of [81 +/- 17 (stat.) +/- 9 (syst.)] SNU. After two years of recordi ng the solar neutrino flux with the GALLEX detector, the combined resu lt from 30 solar runs (GALLEX I + GALLEX II) is [79 +/- 10 (stat.) +/- 6 (syst.)] SNU (1 sigma). In addition, 19 ''blank'' runs gave the exp ected null result. GALLEX neutrino experiments are continuing.
