摘要：

We present the results of a study of KL0 decays observed in the CERN 1.1-m3 heavyliquid bubble chamber. About 75 000 frames were scanned, and yielded some 7500 examples of isolated KL0 decays to charged particles. Based on a sample of 4000 events in a restricted fiducial region, the following branching ratios were found: N(KL0→π±μν)N(KL0→π±eν)=0.648±0. 030, N(KL0→π+π-π0)N(KL0→all charged) =0.157±0.010. © 1969 The American Physical Society.
