Popis: | The slopes of the noninvariant center-of-mass energy spectrum of negative pions in inelastic collisions of {ital d}, {alpha}, C nuclei with C and Ta targets at 4.2{ital A} GeV/{ital c} are studied. The temperatures of the negative pion are obtained using the Boltzmann distribution. The two-temperature shape of c.m. energy spectra is observed. The values of temperature do not depend significantly both on collision centrality'' and on atomic weight of the projectile nuclei. The experimental results are compared with the quark-gluon string model. The influence of resonances and directly produced pions on temperature values is studied. |
