The Anatomy of the Knee and Gamma-Families

It is shown that the fine stucture of the cosmic ray energy spectrum in the knee region, if explained by the Single Source Model (SSM), can, in principle, be clearly revealed and magnified in the size spectrum of extensive air showers (EAS) associated with gamma families. Existing experimental data on EAS at mountain level give support to this hypothesis.Comment: 4 pages, 3 figures, to appear in the Proceedings of 14th International Symposium on Very High Energy Cosmic Ray Interactions, Weihai, China, 15-22.08.06, Nucl.Phys.B (Proc.Suppl.), 200
