Cosmic-ray-induced nuclear interactions are observed by emulsion chambers exposed on Mt. Chacaltaya, Bolivia (5,200m above sea level). Photons from nuclear interactions are detected and measured which occurred within the petroleum pitch layer (1/3 nuclear mean free path), set 150 cm above the emulsion chamber. Photons of energy ≳ 100 GeV are detected in each event, the highest detected photon energy being 40 TeV. 350 events are found to contain 4 or more photons, whose energy sums, ΣE_γ, range from 5 TeV up to 500 TeV (corresponding E_0 estimates being 20 → 3000 TeV), and are adopted for detailed analysis. The highest detected photon p_T is 2.5 GeV/c. Multiplicity-, energy-, angular-, p_T-, and other related distributions of the photons are presented, comparison is made with the accelerator data, and some discussions are given.
