Detection of Muons, and K0L Mesons from e+e- collisions using the endcap RPC module in the Belle detector

The BELLE experiment at KEKB has collected beam collision data from 1 June through 4 August 1999, corresponding to an integrated luminosity of 25 pb

, and the data contain approximately 10,000 e
