An estimate of the temperature of protons andπ− mesons in central He−Li, He−C, C−C, C−Ne, C−Cu, C−Pb, O−Pb, Mg−Mg interactions is presented. The results indicate an increase of the proton temperature with increasing mass numbers of projectile and target nuclei (Ap,AT) fromTp=(118±3) MeV for He−Li toTp=(141±2) MeV for C−Pb. The temperature ofπ− mesons does not depend onAP,AT andTπ≃95 MeV. A satisfactory fit forπ− mesons in C−Cu, C−Pb, O−Pb, Mg−Mg collisions can be achieved by using a form involving two temperatures,T1 andT2. The relative yield of the high temperature component (T2) is ≅24% for C−Cu, C−Pb, and Mg−Mg interactions. The observed results forTP in C−Ne, C−Cu and C−Pb collisions are consistent with the prediction of the thermodynamic hagedorn model.

The cross sections of inelastic interaction of 22Ne with C, Al, Cu and Pb targets have been measured at an incident momentum of 4.1 GeV/c per nucleon. The following results have been obtained: 1060 +- 50 mb; 1520 +- 70 mb; 2150 +- 100 mb and 3900 +- 200 mb, respectively. The approximation of the dependence of the cross sections on the mass numbers of interacting nuclei and the measurement procedure are presented

Experimental data on angular distributions of secondaries in central interactions of carbon nuclei (4.5 GeV/c per nucleon) with copper and lead nuclei are given. Experiment was carried out on incident beam of synchrophasotron. Secondary particles are detected with counters. Angle between the axis of these counters and beam directions varies from 15 to 90 degrees. Target was oriented relative to the beam so, that absorption of particles in it escaping at an angle of 60 degrees may be minimum. This position does not change during measurements. Target thicknesses are the following: copper - 0.92 mm, lead -1.0 mm. At the 3-5% accuracy of measurements within 15-90 deg angle range to the beam direction no anomaly in angular distribution has been discovered which could serve as an evidence of shock wave appearance
