Abstract
The traversal of a total of 100 meters of lead by penetrating particles has been studied at an underground depth of 8.4× g with a cloud chamber containing 2.54-cm lead plates. The observed probability for an energy transfer greater than ev to the soft component is 3.0(±0.7)× per g of lead. Knock-on, bremsstrahlung, and pair-production processes are calculated to give a probability of 2.1× per g of lead. Therefore, the above electromagnetic phenomena account for nearly all of the high energy soft secondaries produced by -mesons of energy ∼ ev.
