OSTI ID:6924393
The Soudan 2 surface-underground cosmic ray experiment can simultaneously measure surface shower size, underground muon multiplicity, and underground muon separation for ultra high energy cosmic ray showers. These measurements are sensitive to the primary composition. Analysis for energies from 10[sup 1] to 10[sup 4] TeV favors a light flux consisting of predominantly H and He nuclei.
