PICCIONI 1948

Piccioni, O.;
Search for Photons from Meson-Capture
Phys. Rev. 74 (1948) 1754;

Abstracts
High energy photons (about 50 MeV) associated with mesons stopped in iron have been searched for. The experimental evidence shows that no such photons arise from the capture of negative mesons or from the free decay of positive ones.
