Forecasting of radiation fields at relativistic ion accelerators

The results of comparison of experimental data with results of calculations of differential characteristics of high-energy hadron radiation fields generated by light relativistic ions in targets are presented. The calculation of angular and energy-angular distributions of the secondary hadrons from differential targets irradiated by protons, α-particles and 12C ions in energy range from one to several GeV per nucleon showed that the agreement of the algorithm used with experiments is not worse at least than the statistical model based programs but the computer time is essentially less. 19 refs.; 11 figs.; 1 tab
