| Popis: | In this paper, we present a model of calculation with respect to the interactions of high-energy nuclei with matter. Based on this model, we obtain results on energy and angular spectra of the n- and π−-particles produced in collisions of deuterium and tritium nuclei at energiesTd=1 GeV/nucleon with light targets such as Li, Be. We have also estimated the production yields of neutrons and π−-mesons in targets of various radii, as well as mean energies of these these particles. Summarizing, we find that the lithium target of radiusR=10−12 cm for which the energy cost eπ to produce one π−-meson is estimated as 6.7 GeV/π for a d-beam and 5.3 GeV/π for a t-beam is the most preferred pion-production target. |
