摘要：

Electron antineutrino interactions above the inverse beta decay energy of protons (E-(nu) over bare > 1.8 MeV) were looked for with the Borexino counting test facility (CTF). One candidate event survived after rejection of background, which included muon-induced neutrons and random coincidences. An upper limit on the solar (nu) over bar (e) flux, assumed having the B-8 solar neutrino energy spectrum, of 1.1 x 10(5) cm(-2) s(-1) (90 % C.L.) was set with a 7.8 ton x year exposure. This upper limit corresponds to a solar neutrino transition probability, nu(e) -> (nu) over bar (e) of 0.02 (90% C.L.). Predictions for antineutrino detection with Borexino, including geoneutrinos, are discussed on the basis of background measurements performed with the CTF.
