Abstract
The time anomaly of neutrino events observed in the KARMEN detector at the ISIS facility is discussed. We show that beam-correlated neutron events are not completely suppressed by the KARMEN lower energy cut and could cause t he observed deviation of the measured time distribution from an exponential curve with tau = 2.2 mus.
