Abstract
In the RUNJOB Russian-Japanese balloon experiment, tracks of primary singly charged particles are detected in approximately half the events related to the proton ones. During repeated processing of the experimental data obtained when exposing RUNJOB-3B, 6A, 11A, and 11B X-ray emulsion chambers (XRECs) using the new method for searching primary cosmic particles, approximately 50% of tracks of primary singly charged particles as before were not detected in the group of events related to the proton ones with primary particle energiesE 0 > 20 TeV and zenith angle tan θ ≤ 5. In this paper,we present a new method for searching and tracing particles in the XREC; characteristics of processed events (the energy, zenith angle, and particle penetration depth in the XREC before the interaction) are given.
