Phys. Rev. D 61, 012001 (1999) [7 pages]Determination of neutrino incoming direction in the CHOOZ experiment and its application to supernova explosion location by scintillator detectorsReceived 10 June 1999; published 6 December 1999 The CHOOZ experiment has measured the antineutrino flux at about 1 km from two nuclear reactors to search for possible ν̅ e→ν̅ x oscillations with mass-squared differences as low as 10-3 eV2 for full mixing. We show that the analysis of the ∼2700 ν̅ e events, collected by our liquid scintillation detector, locates the antineutrino source within a cone of half-aperture ≈18° at the 68% C.L. We discuss the implications of this result for locating a supernova explosion. © 1999 The American Physical Society URL:
