Gamma-ray families with halos: Main characteristics and possibilities of using them to estimate the p+He fraction in the mass composition of cosmic rays at energies 1–100 PeV

Characteristics of γ-ray families with halos (XREC, Pamir) and data of experiments with EAS are analyzed to estimate the proton and helium (p+He) fractions in the primary cosmic radiation at E0 = 1–100 PeV. It is shown that at energies E0 ∼ 1–100 PeV the fraction of p+He remains significant, namely,...
