ON SOME INTERACTION CHARACTERISTICS OF VERY HIGH-ENERGY PARTICLES AND THEIR INTERPRETATION FROM THE VIEWPOINT OF THE HYDRODYNAMICAL THEORY OF MULTIPLE PARTICLES PRODUCTION
S>Landau, using the idea stated by Fermi, employed relativistic hydrodynamics in describing very high energy particle collision. The first attempts to compare the conclusions of hydrodynamical theory with experimental data on the multiplicity and angular and energy distributions of secondary particles already showed that the hydrodynamical theory satisfactorily described many multiple process characteristics. By comparison of the theory with experimental data taken from the analysis of showers recorded in photographic emulsion, a number of essential additional assurnptions were made. These assumptions caused a certain obscurity of the conclusions. For example, it was assumed that the collision of nucleons with heavy nuclei took place in the coordinate system in which notion of substance was symmetrical. Extensive shower analysis carried out on the assumption that the nuclear interaction cross section is independent of energy shows that the formal part of the hydrodynamical theory is incomplete.
