The neutrino experiment KARMEN, a 56 t scintillation detector at the spallation source ISIS in England, has searched for ν̄μ→ ν̄e oscillations at a distance of 17.6 m from the spallation target. Neutrinos were produced from π and μ decay at rest with an endpoint of 52.8 MeV of the neutrino energy. ν̄e were detected through inverse beta decay on free protons of the scintillator with almost no cosmic ray induced background. Results will be shown for data taken from Feb. 1997 to Mar. 2000, after a major upgrade of the experiment. The LSND experiment ran for 6 years at a distance of 30 m from the target of LANSCE at Los Alamos and observed an excess of events consistent with ν̄μ→ ν̄e oscillations. Results from the entire LSND data sample will be presented, which suggest that neutrino oscillations occur with a ∆m in the range 0.2-10 eV/c and that at least one neutrino has a mass greater than 0.4 eV/c. Exclusion limits from KARMEN-2 will be compared to the positive oscillation signal from the LSND experiment and the statistical compatibility will be addressed. 1. The Experimental Configuration
