A SEARCH FOR DELAYED PHOTONS FROM STOPPED SEA-LEVEL COSMIC RAY MESONS.
Abstract
If the meson disintegrates into a photon and an electron, the stopping of a meson and its subsequent decay should give rise to a delayed 50 Mev photon. Delayed coincidences were sought between the stopped meson and the photon, detected by its materialization in a Pb sheet (calculations are presented of the photon detection efficiency for various lead thicknesses and photon energies of 20, 40 and 60 Mev.; the electron range-energy curves used in the calculation are also shown).
