Abstract

Experimental results on the production of two or three heavy (Z⩾10) fragments in the ²²Ne + Au collisions at 60 MeV/u are presented; the three fragment requirement selects large linear momentum transfer (70%) and large excitation energy (3–5 MeV/u.m.a.) for the incomplete fusion system. An analysis of the relative velocities and angles in the centre of mass of the three fragments shows that a sequential process with short time span and mutual influence between the two binary decays is favoured. A confirmation is found in the comparison of the correlation functions V_ij and Θ_ij with the results of Coulomb trajectories calculat ions including various time scales.

Post breakup dynamical evolution of fragments produced in nuclear multifragmentation

For instance, the results reported in Refs. [8,9] suggest that the deexcitation of the primary fragments takes place concomitantly with their creation, whereas a two-stage scenario, considering a prompt breakup followed by the deexcitation of the primordial hot fragments, has proven to be quite successful in describing many experimental observations [2,15–17,21,22]. The situation from the experimental point of view is perhaps even more complicated, as the experiments detect the reaction products after a time span of several orders of magnitude larger than the time scale associated with the primary fragment emission [1,5,23–29]. Owing to this fact, most of the quantities observed experimentally are strongly skewed by the decay of the hot fragments produced in the stages one intends to investigate [15,17,21,22,30].
The deexcitation of the primary hot fragments, produced in the breakup of an excited nuclear source, during their propagation under the influence of their mutual Coulomb repulsion is studied in the framework of a recently developed hybrid model. The latter is based on the Statistical Multifragmentation Model (SMM), describing the prompt breakup of the source, whereas the particle emission from the hot fragments, that decay while traveling away from each other, is treated by the Weisskopf-Ewing evaporation model. Since this treatment provides an event by event description of the process, in which the classical trajectories of the fragments are followed using molecular dynamics techniques, it allows one to study observables such as two-particle correlations and infer the extent to which the corresponding observables may provide information on the multifragment production mechanisms. Our results suggest that the framework on which these treatments are based may be considerably constrained by such analyses. They imply that information obtained from these model calculations may provide feedback to the theory of nuclear interferometry. In particular, our results do not support the hypothesis that the total momentum of the selected pair of particles used in the two-particle correlations remains constant during the post-breakup dynamics. Furthermore, the correlations may be appreciably affected by this fact. We also found that neutron deficient fragments should hold information more closely related to the breakup region than neutron rich ones, as they are produced in much earlier stages of the post breakup dynamics than the latter.
Time-scale analysis of three-fragment emission in the 12.7 GeV 4He + 197Au reaction

At excitation energies below 1 MeV/u, dominant deexcitation processes are binary fission and evaporation of light particles (n, p, α). For higher excitation energies, there is an increasing probability for production of intermediate-mass fragments (IMF-s) (Lips et al., 1994a; Hirata et al., 2002) and events ending with three and more fragments (Grabež and Gerc, 1988; Bougault et al., 1989; Bizard et al., 1993; Lips et al., 1994b; Vardaci et al., 2000). The type of fragment emission mechanism affects strongly the time-scale for heavy and IMF emission.
The time-scale for emission of three fragments (Z ≥ 8) in the 12.7 GeV ⁴He + ¹⁹⁷Au reaction has been studied using a sandwich configuration of the Makrofol polycarbonate track detector. In events with different multiplicity of heavy fragments (Z > 20), the differences of the correlation functions for relative angle and relative velocity between pairs of fragments have been studied in order to determine the fragment emission-time scale. A sequential decay mechanism for the excited residual nuclei was found to be consistent with experimental data. It was determined that the fragment emission-time decreased with decreasing multiplicity of heavy fragments: from 1000 fm/c for events with two heavy fragments, through 300 fm/c for events with one heavy fragment, to 40 fm/c for events with no emission of heavy fragments.
Nuclear multifragmentation and phase transition for hot nuclei
2008, Progress in Particle and Nuclear Physics
This review article is focused on the tremendous progress realized during the last fifteen years in the understanding of multifragmentation and its relationship to the liquid–gas phase diagram of nuclei and nuclear matter. The explosion of the whole nucleus, early predicted by Bohr [N. Bohr, Nature 137 (1936) 351], is a very complex and rich subject which continues to fascinate nuclear physicists as well as theoreticians who extend the thermodynamics of phase transitions to finite systems.
Search for mass-symmetric ternary fission in the reactions 14N(53 A MeV) + 197Au an 232Th
2002, Nuclear Physics A
Ternary fission of heavy hot composite systems with excitation energies of 1.5–2.5 MeV $/$ amu has been studied in the reactions of ¹⁴N(53 $A$ MeV) with ¹⁹⁷Au and ²³²Th. The ternary yields have been explored as a function of the charge $Z_{L}$ of the lightest fragment: while $Z_{L}$ increases from 6 to 25, the cross sections decrease from 5 to 0.08 mb for N $+$ Au and from 15 to 0.8 mb for N $+$ Th. The velocity vector $v →_{L}$ of the lightest fragment has been investigated in the rest frame of the other two heavier fragments. Two different components are observed: (i) an isotropic one with values of $v_{L}$ corresponding to the Coulomb repulsion from the combined heavier fragments before separation and, (ii) an anisotropic contribution with the lightest fragment emitted with lower $v_{L}$ perpendicular to the scission axis of the two heavier fragments. The latter component is distinguished from the isotropic one by an enhanced fraction of mass-symmetric ternary events and by up to 50 MeV lower total kinetic fragment energies. These features are indicative of a collinear stretched scission configuration, where the lightest fragment is positioned between the two heavier ones.
Fragment emission from modestly excited nuclear systems
1996, Nuclear Physics A
Fragment emission patterns occurring in nuclear systems of modest excitation are studied. Exclusive measurement of fragment emission in $^{14} N+^{197} Au$ reactions at $E A = 100, 130 and 156 MeV$ allows selection of central collisions where a single source dominates the decay. Low threshold measurement of IMF emission for these events allows investigation of the influence of detector threshold effects. The time scale of fragment emission is deduced using fragment-fragment velocity correlations. Comparisons are made to the predictions of a statistical decay model.
Nuclear disassembly time scales using space-time correlations
1995, Physics Letters B
The lifetime, τ, with respect to multifragmentation of highly excited nuclei is deduced from the analysis of strongly damped Pb + Au collisions at 29 MeV/u. The method is based on the study of space-time correlations induced by “proximity” effects between fragments emitted by the two primary products of the reaction and gives the time between the reseparation of the two primary products and the subsequent multifragment decay of one partner. A lifetime significantly longer than the interaction time is found. It is compared with time scales corresponding to different types of dynamical instabilities which may be responsible for nuclear disassembly.
