“…Our previous study of the 40 Ca + 40 Ca at 35 MeV/nucleon focused on the multi-fragment exit channels and led to the conclusion that even the most violent and most central collisions were binary in nature [31]. Similar conclusions on the dominant binary nature of reactions with 35 MeV/nucleon 24 Mg projectiles were reported by Larochelle et al [32].…”

The de-excitation of alpha-conjugate nuclei produced in reactions of 35 MeV/nucleon 40 Ca with 40 Ca has been investigated. Particular emphasis is placed on examining the dynamics of collisions leading to projectile-like fragment exit channels. A general exploration of the reaction systematics reveals the binary dissipative character of the collisions and a hierarchy effect similar to that seen for heavier systems. Investigation of the subset of events characterized by a total α-conjugate mass (α particles plus α-conjugate fragments) equal to 40 and atomic number equal to 20 reveal a dominance of α-conjugate exit channels. The hierarchy effect for these channels leads to the production of α-clustered neck structures with potentially exotic geometries and properties.

“…It should be commented here that in the QMD used in Ref. [12] the kinetic energy does not include the zero-point oscillation energy though the density is the sum of Gaussian wave packets, and hence the extension formulated in the previous section is not directly applicable to this QMD.…”

“…12 of Ref. [12] in which there are two components, one with small S component corresponds to the events with a large IMF and many small fragments while the second component is due to the events with several IMFs produced. On the other hand, in the usual AMD result, the first component is missing because most events are binary.…”

“…In order to compare the calculated results by AMD and AMD-V with the experimental data [12], it is necessary to apply the experimental filter. In experiment, only the completely detected violent events are used for the analysis by selecting the events with the detected total charge Z tot ≥ 34 and the detected charged particle multiplicity M c > ∼ 10.…”

“…[12], this reaction system was analyzed with various models, including the quantum molecular dynamics (QMD) [6], the statistical sequential decay model (gemini) [13], and the simultaneous multifragmentation model of Gross [14]. None of these models reproduces the α particle multiplicity M α which is as large as 5.2.…”

Antisymmetrized molecular dynamics of wave packets with stochastic incorporation of the Vlasov equation

1996

On the basis of the antisymmetrized molecular dynamics (AMD) of wave packets for the quantum system, a novel model (called AMD-V) is constructed by the stochastic incorporation of the diffusion and the deformation of wave packets which is calculated by Vlasov equation without any restriction on the one-body distribution. In other words, the stochastic branching process in molecular dynamics is formulated so that the instantaneous time evolution of the averaged one-body distribution is essentially equivalent to the solution of Vlasov equation. Furthermore, as usual molecular dynamics, AMD-V keeps the many-body correlation and can naturally describe the fluctuation among many channels of the reaction. It is demonstrated that the newly introduced process of AMD-V has drastic effects in heavy ion collisions of 40 Ca + 40 Ca at 35 MeV/nucleon, especially on the fragmentation mechanism, and AMD-V reproduces the fragmentation data very well. Discussions are given on the interrelation among the frameworks of AMD, AMD-V and other microscopic models developed for the nuclear dynamics.
