Abstract

The problem of studying the spectra of deuterium and tritium nuclei is a part of a more general problem of studying the processes of cosmic-ray acceleration and propagation. In recent years, various experiments have revealed the noticeable differences in spectra of cosmic-ray components, as well as the presence of an additional “knee” in their magnetic–rigidity spectrum. These effects require explanation. Information about the spectra of high-energy deuterons and, perhaps, tritons is needed for finding a solution for this problem. These particles are secondary, and analysis of their spectra can help make a choice among different hypotheses. A method is proposed for separating hydrogen isotopes in the high-energy region based on analysis of the hadronic cascade shape in a deep ionization calorimeter that will be used in the future OLVE-HERO experiment. The feasibility of such separation has been shown by processing results of the SOKOL-2 experiment.
