Proton and ion beams with the initial energy between 0.2 AGeV and 10 AGeV were analyzed with respect to the neutron production in different targets, the number and spatial distribution of fission acts and the energy deposited in uranium targets. In this energy range two models for the hadronic inelastic interaction are suitable: bertini cascade and binary cascade. In thin and medium thickness targets both models produce results in good agreement with the experimental data. In very thick targets the use of binary cascade gives neutron production about two times lower than the bertini cascade and the experimental data. For this reason the last model was chosen for the modeling of the hadronic inelastic interaction. In large uranium target the total number of fission acts ( the energy deposited) per incident particle, reported to the energy spent to accelerate the particle and to the total number of fission acts (the energy deposited) per incident proton with the same energy per nucleon increases with the mass number of ion. Such dependence for the number of fission acts shows a quick rise for ions until Fe, followed by a slower increase. The simulations performed show that from the point of view of the energetic balance (neglecting the problem of a suitable beam intensity) it seems more useful to accelerate at the same energy per nucleon, ions with mass number between Ca and Fe, than protons.

Cross sections of spallation reactions of 181 Ta, 197 Au, 207 Pb, 209 Bi, 232 T h, 238 U heavy metals induced by deuterons with energy of 2, 2.94, 3.5 GeV were determined. The deuteron beams were extracted from the Nuclotron accelerator at the Laboratory of High Energy Physics, JINR, Dubna, Russia. Spallation reactions cross sections were measured using solid state nuclear track detectors (SSNTD) and activation gamma-spectroscopy. Due to the lack of cross sections data in the range of high energies the experimental results could be added in the international database.
