Abstract
Experimental muon number distributions in EAS obtained at Moscow State University are analysed to estimate the primary mass composition at e nergies before and after knee. The mass composition before the knee co rresponds to the normal one (as at E(0) similar to 10(12) eV), while e xperimental data after the knee are in agreement with the assumption t hat normal composition becomes enriched slowly by heavy nuclei, as als o supported by contemporary diffusion models.
