Spectrum of Galactic Particles in the 10‒500 TeV Energy Range from the Results of Reprocessing of the Data Obtained by the Stratospheric X-ray Emulsion Chamber Method

Abstract

We present a spectrum of primary galactic particles with energies of 10 TeV < E₀ < 500 TeV, obtained from the data of reprocessing of events related to nucleon‒nucleus interactions measured in four X-ray emulsion chambers (RECs) exposed in the stratosphere at ∼10 g/cm² for 6‒7 days in the Russian‒Japanese RUNJOB balloon experiment. The spectrum agrees within statistical errors with the proton spectrum published on the results of the final processing of the RUNJOB experiment [1]. The presented spectrum of galactic particles includes events with found and missing single-charged primary particles in nucleon‒nucleus interactions, and is compared with the spectrum constructed only from events with detected primary protons and the final spectrum of the cosmic ray proton component of the RUNJOB experiment.
