Popis: KARMEN, the Karlsruhe-Rutherford Medium Energy Neutrinoexperiment at the pulsed spallation neutron facility ISIS uses the beam stop neutrinos νμ, νe and νμ from π+ and μ+ decay at rest to search for neutrino oscillations in the appearance channels νμ → νe and νμ → νe. The signature for both oscillations is based on charged current neutrino nuclear interaction spectroscopy in a high resolution 56 t liquid scintillator calorimeter. The detector system has been upgraded with an additional veto layer during 1996 to eliminate cosmogenic background. This report describes results for the oscillation channel νμ → νe based on data acquired from June 1990 to August 1995 and the first data of 1997 with the new veto system in operation.
