A good parameter for evaluating the stopping power of the collision is the vartl quantity, that is, the ratio between the variances of the transverse and longitudinal rapidity distributions, as suggested by the FOPI collaboration [25][26][27]. In our calculation we get values around 0.75, not much different at the two beam energies, comparable to data although no experimental filter is included.…”

Isospin emission and flow at high baryon density: A test of the symmetry potential

et al. 2010

High-energy heavy-ion collisions are studied to access nuclear-matter properties at high density. Particular attention is paid to the selection of observables sensitive to the poorly known symmetry energy at high baryon density, of large fundamental interest, even for the astrophysics implications. Using fully consistent transport simulations built on effective theories, we test isospin observables ranging from nucleon and cluster emissions to collective flows (in particular the elliptic, squeeze-out, part). The effects of the competition between stiffness and momentum dependence of the symmetry potential on the reaction dynamics are thoroughly analyzed. In this way we try to shed light on the controversial neutron and proton effective mass splitting at high baryon and isospin densities. New, more exclusive, experiments are suggested.

“…We can use this interpretation to understand the system mass-dependence of the energy of transition from ∆ = 1 /2 to ∆ = 1 scaling presented in [53] Radial expansion in central heavy-ion collisions occurs after significant compression of the incoming nuclear fluid, and as such depends not only on static nuclear matter properties such as incompressibility, but also on transport properties such as the degree of stopping achieved in the collision [78]. The latter increases with the mass of the colliding nuclei, as shown in [79] Conclusions We have shown that, for finite systems, the largest cluster size distribution in critical aggregation models is an admixture of the two asymptotic distributions observed far below and above the critical region.…”

Nuclear Multifragmentation Time Scale and Fluctuations of the Largest Fragment Size

et al. 2013

Distributions of the largest fragment charge, Zmax, in multifragmentation reactions around the Fermi energy can be decomposed into a sum of a Gaussian and a Gumbel distribution, whereas at much higher or lower energies one or the other distribution is asymptotically dominant. We demonstrate the same generic behavior for the largest cluster size in critical aggregation models for small systems, in or out of equilibrium, around the critical point. By analogy with the timedependent irreversible aggregation model, we infer that Zmax distributions are characteristic of the multifragmentation time-scale, which is largely determined by the onset of radial expansion in this energy range. Introduction In central heavy-ion collisions at beam energies of ∼20-150 MeV/A multiple production of nuclear fragments can be observed, compatible with the quasi-simultaneous break-up of finite pieces of excited nuclear matter [1][2][3][4][5][6][7]. This so-called "nuclear multifragmentation" is a fascinating process [8] which has long been associated with a predicted liquid-gas coexistence region in the nuclear matter phase diagram at sub-critical temperatures and sub-saturation densities [9][10][11]. Statistical [12][13][14][15][16][17][18][19] and dynamical [20][21][22][23][24] aspects have been widely studied, and evidences supporting equally well either a continuous phase transition of the liquid-gas universality class [13,14,[25][26][27][28][29][30], a discontinuous ("first-order") transition occurring within the coexistence region [29][30][31][32][33][34][35], or indeed the survival of initial-state correlations in a purely dynamical picture [36,37] have been presented. This state of affairs well demonstrates the difficulty of quantitatively identifying a phase transition in small systems such as atomic nuclei, where finite-size effects blur the nature of the transition [38][39][40] whose order may indeed change with the size of the system [29,30], along with the importance of long-range Coulomb forces [4,19,41,42], and presence of dynamical effects such as radial flow [43][44][45][46][47][48][49].In this context we have tried to establish generic features of multifragmentation in order to deduce its nature in a less model-dependent way. In our previous works [50], we used the model-independent universal fluctua-
