A regeneration experiment exploring KS−KL interference in the decay modes KS,L→π+π− and KS,L→π±l∓ν (l=μ or e) has been performed at the Brookhaven National Laboratory alternating-gradient synchrotron. The regeneration phases in carbon obtained from the time-dependent charge asymmetry of the Ke3 and Kμ3 modes are in good agreement and yield a combined result ϕf≡argi[f(0)−f(0)]=−40.9°±2.6° at the average K0 momentum of 7.5 GeV/c.
