HighlightsWe analysed the SOKOL space experiment results.Proton and deuteron showers in the calorimeter were simulated.High energy deuterons and protons were separated by means of neural network.The deuterium to proton ratio in cosmic rays above 500GeV/n was determined.The significant increase of deuterium to hydrogen ratio was discovered.

    AbstractWe present the first measurement of the deuterium to proton ratio in cosmic rays, above 500GeV/nucleon. The data were obtained as part of the SOKOL satellite experiment. The cascade curves generated by single charged particles in the calorimeter were analysed. A hadronic showers’ simulation was performed. Simulated and experimental cascade curves were compared. Neural networks were used to select proton and deuteron events. The deuterium to proton ratio was evaluated as 0.114±0.023, whilst the deuterium to helium ratio was evaluated as 1.64±0.30 for energies between 500and2000GeV/n.
