KNOCK-ON ELECTRONS FROM COSMIC-RAY $mu$-MESONS

Journal Article · · Proc. Phys. Soc. (London)
A cloud chamber study was made of the electron secondaries produced by fast mu mesons in iron aad lead plates and cloud chamber gas. The mean probability of a meson emerging from a plate accompanied by a single electron was accurately determined for mesons in the momentum range 0.5 to 200 Bev/c. This probability is 9.0 plus or minus 0.4% for 55 g cm/sup -2/ iron and 5.80 plus or minus 0.15% for 11.5 g cm/sup -2/ lead. A search was made for any anomalous dependence of electron production upon primary momentum or sign of charge but none was detected. (auth)
