© 2019, Pleiades Publishing, Ltd.We present the energy dependence of the cross section for the inelastic interaction of protons with tungsten in the energy range from an order of 1 to hundred GeV using the data of the PAMELA space experiment. It was intended for the precision measurements of the cosmic ray fluxes of different nature and include a set of detectors for the reliable determination of the particle characteristics. We present the comparison of the obtained results with the measurements at accelerators and with existing theoretical models. The results of the work can be demanded for the development of numerical models describing particles’ interactions.

We have used different types of harmonic analysis, such as Fourier and wavelet analysis. The time profiles and amplitude dependences for the rigidities of cosmic ray particles from ~300 MV to tens of GV were obtained. It is shown that the amplitude-rigidity dependence cannot be described by a power law at low energies, the amplitude decreases with decreasing rigidity starting from ~ 1 GV. For a physical interpretation, we have studied the relationship between the 27-day variations of GCR and heliospheric parameters: solar wind velocity and heliospheric magnetic field.
