Multifragmentation in Relativistic Heavy Ion Reactions
Multifragmentation is the dominant decay mode of heavy nuclear systems with excitation energies in the vicinity of their binding energies. It explores the partition space associated with the number of nucleonic constituents and it is characterized by a multiple production of nuclear fragments with intermediate mass. Reactions at relativistic bombarding energies, exceeding several hundreds of Me...
متن کاملMicroscopic Theory of Multifragmentation in High Energy Heavy-ion Collisions
We introduce a novel N-body approach to describe heavy ion collisions. The nucleons are represented as Gaussian wave packets in configuration and momentum space. They interact via a combination of a Skyrme type potential and a Uehling-Uhlenbeck two-body scattering mechanism. This theory keeps track of the correlations and therefore allows for a selfconsistent theoretical description of the enti...
متن کاملFermionic Molecular Dynamics: Multifragmentation in Heavy–ion Collisions and in Excited Nuclei
How multifragmentation happens in heavy ion collisions is still a matter of debate. Explanations reach from nucleation over self organization, spinodal decomposition to cold break–up and survival of initial correlations. For an overview see ref. [1]. A key question is the time scale of the reaction. Slow processes like nucleation or self organization are hindered if the expansion of the whole s...
متن کاملStatistical Multifragmentation of Non-Spherical Expanding Sources in Central Heavy-Ion Collisions
We study the anisotropy effects measured with INDRA at GSI in central collisions of 129Xe+natSn at 50 AMeV and 197Au+197Au at 60, 80, 100 AMeV incident energy. The microcanonical multifragmentation model with non-spherical sources is used to simulate an incomplete shape relaxation of the multifragmenting system. This model is employed to interpret observed anisotropic distributions in the fragm...
متن کاملIsospin Effect on the Process of Multifragmentation and Dissipation at Intermediate Energy Heavy Ion Collisions
In the simulation of intermediate energy heavy ion collisions by using the isospin dependent quantum molecular dynamics, the isospin effect on the process of multifragmentation and dissipation has been studied. It is found that the multiplicity of intermediate mass fragments Nimf for the neutron-poor colliding system is always larger than that for the neutron-rich system, while the quadrupole o...
