ANGULAR PRODUCTION OF FAST AND SLOW PARTICLES IN LI-7-EMULSION INTERACTIONS AT 26 GEV

The angular distributions of the relativistic particles emitted in the inelastic interactions of Li-7-nuclei were studied in terms of the ps eudorapidity variable. These distributions are fitted by Gaussian curv es. The distributions are compared with the distributions obtained usi ng C-12-emulsion at similar energy and others incident beams at higher energies. The dispersion of these distributions is found to be indepe ndent of the size of the interacting systems at similar energies. The dispersions sigma and the average pseudorapidities [eta] increase when the energy of the incident beam increases. The angular distributions of the emitted grey and black particles are studied in the frame of th e Maxwell-Boltzmann distribution.
