“…The results for Au+Au collisions for all beam energies at midrapidity are shown in Fig. 2 For (dET /dη)/(0.5Npart) (a), data are shown from FOPI [27], E802 [28], NA49 [29,30] Figure 3b shows the same for (dN ch /dη)/(0.5N part ). Previous measurements in fixed target h+A collisions showed that the total charged particle multiplicity does scale well as a function of N part in the range of 10 ≤ √ s N N ≤ 20 GeV [36].…”

Measurements of midrapidity charged particle multiplicity distributions, dN ch /dη, and midrapidity transverse-energy distributions, dET /dη, are presented for a variety of collision systems and energies. Included are distributions for Au+Au collisions at For all A+A collisions down to √ s N N = 7.7 GeV, it is observed that the midrapidity data are better described by scaling withNqp than scaling with Npart. Also presented are estimates of the Bjorken energy density, εBJ, and the ratio of dET /dη to dN ch /dη, the latter of which is seen to be constant as a function of centrality for all systems.

“…Heavy ion reactions at relativistic energies offer a wide range of possibilities to study the multi-fragment decay of highly excited nuclei [1][2][3][4][5][6][7][8]. In collisions of heavy nuclei at incident energies exceeding values of about 100 MeV per nucleon [2], highly excited and equilibrated spectator systems are formed which decay by multifragmentation [9] in good agreement with statistical predictions [10,11].…”

“…The yields of particles not stopped in the CsI(Tl) detectors was very low at these backward angles and did not affect the deduced isotope ratios. The contamination of lithium yields by two- 4 He events (decay of 8 Be) was estimated to be 2% and ignored. However, because of the presumably different shapes of 3 He and 4 He spectra at low energies (cf.…”

Breakup temperatures were deduced from double ratios of isotope yields for target spectators produced in the reaction 197 The good agreement with the breakup temperatures measured previously for projectile spectators at an incident energy of 600 MeV per nucleon confirms the universality established for the spectator decay at relativistic bombarding energies. The measured temperatures also agree with the breakup temperatures predicted by the statistical multifragmentation model. For these calculations a relation between the initial excitation energy and mass was derived which gives good simultaneous agreement for the fragment charge correlations.The energy spectra of light charged particles, measured at θ lab = 150• , exhibit Maxwellian shapes with inverse slope parameters much higher than the breakup temperatures. The statistical multifragmentation model, because Coulomb repulsion and sequential decay processes are included, yields light-particle spectra with inverse slope parameters higher than the breakup temperatures but considerably below the measured values. The systematic behavior of the differences suggests that they are caused by light-charged-particle emission prior to the final breakup stage. Keywords:197 Au projectiles and targets, E/A = 600 and 1000 MeV; measured fragment cross sections, isotopic yield ratios; deduced breakup temperatures, pre-breakup emission; analysis using quantum statistical and statistical multifragmentation models.

“…It is important to note that there are problems with determining both the excitation energy [2,5,7,19] and the temperature [12][13][14][15][20][21][22][23][24][25][26] of multifragmenting systems. After correction for collective expansion, for example, calculated excitation energies for peripheral collisions at high energies must be further reduced by roughly 30% to reproduce experimental data and larger corrections are estimated for energetic central collisions [2,7,19,27]. Collective motion, pre-equilibrium emission and Coulomb barrier fluctuations increase significantly the temperatures deduced from kinetic energy spectra [1][2][3]12,19] while secondary decay modifies the temperatures deduced from excited state populations and isotope ratios [21,22].…”
