Energy spectra of secondary particles in [gamma] families and their sensitivity to the spectrum of primary cosmic rays

Spectra of secondary particles (γ-rays) in γ-families detected in the X-ray chambers in the Pamirs (H = 600 g cm-2) have been analyzed. These γ-ray spectra show a bend at the energy E*γ [asymp] (ΣE γ)min, where (ΣE γ)min is the lowest total energy of γ-rays in the families above which γ-families wer...

Description
Summary:Spectra of secondary particles (γ-rays) in γ-families detected in the X-ray chambers in the Pamirs (H = 600 g cm-2) have been analyzed. These γ-ray spectra show a bend at the energy E*γ [asymp] (ΣE γ)min, where (ΣE γ)min is the lowest total energy of γ-rays in the families above which γ-families were selected. The bend is not related to the knee in the spectrum of primary particles; it is due to the use of the ΣE γ selection criterion. The E γ spectrum slope is sensitive to the spectrum of the primary cosmic rays in the region E γ [greater than or equal to] (ΣE γ)min.
