Abstract

Various flow effects of nuclear and hadronic origin are investigated in nucleus-nucleus collisions. Nuclear emulsion data collected from {sup 84}Kr + Ag/Br interaction at an incident energy of 1.52 GeV per nucleon and from {sup 28}Si + Ag/Br interaction at an incident energy of 14.5 GeV per nucleon are used in the investigation. The transverse momentum distribution and the flow angle analysis show that collective behavior, like a bounce-off effect of the projectile spectators and a sidesplash effect of the target spectators, are present in our event samples. From an azimuthal angle analysis of the data we also see a direct flow of the projectile fragments and of the produced charged particles. On the other hand, for both data samples the target fragments exhibit a reverse flow, while the projectile fragments exhibit an elliptic flow. Relevant flow parameters are measured.

Collective flow by the azimuthal correlation of projectile fragments in relativistic heavy-ion collisions

Journal Article Singh, G; Jain, P - Physical Review, C (Nuclear Physics); (United States)

An analysis that does not require the determination of reaction plane on an event-by-event basis, and involves only azimuthal correlation function of the projectile fragment pairs, has been employed to measure the collective flow of nuclear matter. Using this technique, we study the flow of projectile fragments of charge [ital Z][ge]2 produced in [sup 197]Au induced-emulsion reactions at 10.6[ital A] GeV. The collective flow is observed to be the most pronounced in semicentral collisions. The results are compared with those of [sup 28]Si at 14.5[ital A] GeV, [sup 238]U at 0.96[ital A] GeV, [sup 84]Kr at 1.52[ital A] GeV, andmore » [sup 56]Fe at 1.7[ital A] GeV.« less

Rapidity dependence of entropy production in proton- and nucleus-induced reactions on heavy nuclei

Journal Article Jacak, B; Stoecker, H; Westfall, G - Phys. Rev. C; (United States)

The entropy of hot nuclear systems is deduced from the mass distribution of fragments emitted from high energy proton- and nucleus-induced reactions via a quantum statistical model. It is found that the entropy per baryon, S/A, of intermediate rapidity (''participant'') fragments is higher than the entropy of target rapidity (''spectator'') fragments. The spectator fragments exhibit S/A values of roughly-equal1.8 independent of the projectile energy from 30 MeV/nucleon up to 350 GeV. This value of the entropy coincides with the entropy at which nuclear matter becomes unbound.

Experimental data on the average number of interacting protons in inelastic and central nucleus--nucleus interactions at 3. 6 GeV/nucleon

Journal Article

Experimental data obtained in inelastic and central nucleus--nucleus collisions are presented on the following average multiplicities: the total charged-particle multiplicity , the multiplicity of interacting protons , the multiplicity of interacting protons of the incident nucleus , the multiplicity of interacting nucleons of the target nucleus <..nu../sub t/>, and also the ratios /, where is the average multiplicity of negative pions. The data were obtained in the two-meter streamer chamber SKM-200 exposed in beams of /sup 4/He, /sup 12/C, /sup 16/O, and /sup 20/Ne at energy 3.6 GeV/nucleon in targets of C, Ne, Al, Si, Cu, Zr, and Pb.

Azimuthal correlations of transverse energy for Pb on Pb at 158 GeV/nucleon

Conference Wienold, T; Huang, I

Azimuthal correlations have been studied in heavy ion reactions over a wide range of beam energies. At low incident energies up to 100 MeV/nucleon where collective effects like the directed sidewards flow are generally small, azimuthal correlations provide a useful tool to determine the reaction plane event by event. In the energy regime of the BEVALAC (up to 1 GeV/nucleon for heavy ions) particular emission patterns, i.e. azimuthal correlations of nucleons and light nuclei with respect to the reaction plane, have been associated with the so called squeeze out and sidesplash effects. These effects are of particular interest because ofmore »« less

Charge correlations and transverse momenta observed in multifragmentation of 1 GeV/nucleon Au projectiles

Journal Article Rusch, G; Heinrich, W; Wiegel, B; ... - Physical Review, C (Nuclear Physics); (United States)

We have investigated the fragmentation of [sup 197]Au projectiles at 0.85 to 1 GeV/nucleon in collisions with targets (CH[sub 2])[sub [ital n]], C, and Pb. Using plastic nuclear track detectors all projectile fragments with charge 6[le][ital Z][sub [ital F]][le]77 produced in a collision were observed in coincidence. The combination of C and (CH[sub 2])[sub [ital n]] data allows us to extract the hydrogen component in measured distributions by the use of the statistical subtraction method. Our data show a target dependence of the multifragmentation process which indicates a nonequilibrated source of the fragments and/or the influence of the target nucleusmore »« less
