Abstract: (Elsevier)
Experimental cosmic ray data on hadron interactions are reviewed (Part I). Specific features of cosmic ray experiments and specific methods used are briefly described. The data which may be considered as definitely established and accepted by all cosmic ray investigators are separated from those results which are not yet proved but, being of utmost importance, deserve serious attention. Besides, some indications of possible new phenomena at laboratory impinging energy E L ∼ 10 4 −10 5 GeV are described. Among the most essential suggestions arisen from cosmic ray studies particularly stressed are: first the division of produced particles into two groups — pionization (these constitute an overwhelming majority of final particles) and leading ones — with sharply different kinematic properties; second the tendency of multiple production of particles to proceed via formation of clusters, whose properties correspond to those of a statistical system with temperature of the order of the pion mass.
