| Abstract: | The electron-antineutrino spectrum has been measured at a position 8.75 m from the “point-like” core of the ILL 235U fission reactor, using the reaction e + p → e+ + n. Positrons and neutrons were detected in coincidence by means of a low-background liquid scintillator and a 3He detector system. The observed neutron correlated positron spectrum is consistent with theoretical predictions assuming no neutrino oscillations. Upper limits for the oscillation parameter are presented. |
