To date, much work has been done on the study of coherent diffractive dissociation of π -mesons by protons. In these works, the angles and pulses of secondary particles were mainly measured. There is very little work on the identification of secondary particles. This may be due to difficulties in identifying secondary storm particles in track instruments. In this work, angular, pulse and ionization measurements were carried out on tracks of secondary particles. Strict methods of mathematical statistics for identification of particles and selection of events in photomulsions are described and applied. The results obtained show the reliability and correctness of the method used.
