We estimate the 1.8 MeV luminosity of the Sco-Cen association due to radioactive decay of 26 Al to (4 − 15) 10 −5 ph cm −2 s −1. We propose a low surface brightness , limb brightened bubble for the 1.8 MeV intensity distribution. The detectibility of this distribution with existing γ-ray telescopes is discussed.

In this report a summary of recent developments in the fields of high-energy nuclear interactions (HE 1) and air shower phenomenology (HE 2) is presented. New results from accelerator and cosmic-ray experiments and the progress in the theoretical understanding and simulation are reviewed and their impact on air shower analysis is discussed.
