Abstract: The energy distribution of produced particles in multiple particle production is formulated empirically based on the data of direct observations by accelerator and cosmic-ray experiments at 10(12)-10(14) eV. The formulated distribution indicates violation of the Feynman scaling law, which was shown to be valid in the low energy region of less than or equal to 10(12) eV. That is, the particle density is suppressed in the forward region and enhanced in the central region, compared with the distribution of the Feynman scaling law. The consequences of the formulated distribution, such as multiplicity, inelasticity, etc., are discussed at high energies of less than or equal to 10(15) eV by extrapolation. The distribution is also compared with those of nuclear interaction models which are used widely in simulations of accelerator and cosmic-ray experiments.
