PI(-)MESON AND NUCLEON YIELDS FROM LIGHT TARGETS IRRADIATED BY DEUTERIUM AND TRITIUM NUCLEI BEAMS AT ENERGIES OF 1-GEV NUCLEON/

In this paper, we present a model of calculation with respect to the i nteractions of high-energy nuclei with matter. Based on this model, we obtain results on energy and angular spectra of the n- and pi--partic les produced in collisions of deuterium and tritium nuclei at energies T(d) = 1 GeV/nucleon with light targets such as Li. Be. We have also estimated the production yields of neutrons and pi--mesons in targets of various radii, as well as mean energies of these particles. Summari zing, we find that the lithium target of radius R = 10-12 cm for which the energy cost epsilon(pi) to produce one pi--meson is estimated as 6.7 GeV/pi for a d-beam and 5.3 GeV/pi for a t-beam is the most prefer red pion-production target.
