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

The mean multiplicities of π− mesons and protons originating from pC, dC, αC, and CC interactions at a momentum of p=4.2 GeV/c per projectile nucleon and the distributions of these particles in kinematical variables are presented. These experimental distributions are compared with the corresponding predictions obtained on the basis of the FRITIOF model. It is shown that the FRITIOF version used in the present analysis describes satisfactorily our experimental data.

Preliminary inclusive spectra of negative hadrons, net protons and neutral strange particles are presented, measured by the NA49 experiment in central Pb+Pb collisions at 158 GeV per nucleon. Comparison of their yields with those from the lighter S+S system suggests that the yields scale approximately with the number of participating nucleons.
