Sard, R.D.; Althauss, E.J.;
Test of the Hypothesis that the Sea-Level Cosmic-Ray Meson Disintegrates into a Photon and an Electron
Phys. Rev. 73 (1948) 1251;

Motivation
The hypothesis has been tested by searching for delayed coincidences between the 50 MeV photon, detected by its materialization in a Pb sheet and the arrival of the meson that gets stopped. (Extracted from the introductory part of the paper.).
