“…This interesting phenomenon is not new and was studied extensively a decade ago. For medium mass nuclei, this is a common phenomenon in central or near central collisions at energy we consider here [63,64,65]. The formation of bubble and ring structures during expansion implies that the central density shown in Fig.…”

Using an isospin-dependent transport model, we study isospin effects on two-nucleon correlation functions in heavy-ion collisions induced by neutron-rich nuclei at intermediate energies. We find that these correlation functions are sensitive to the density dependence of nuclear symmetry energy, but not to the incompressibility of symmetric nuclear matter and the medium dependence of nucleonnucleon cross sections. This sensitivity is mainly due to effects of nuclear symmetry energy on the emission times of neutrons and protons as well as their relative emission sequence. We also study the variations of the symmetry energy effects on nucleon-nucleon correlations with respect to the impact parameter, incident energy, and mass number of heavy ion collisions.

“…Besides disks, other exotic shapes have been predicted (174) for hot nuclei and recently observed in BUU or BNV calculations (172,(175)(176)(177)(178)(179). These shapes are donuts or toroids (see Figure 12), and bubbles.…”

“…The issues under consideration in the present study have gained further actuality by a number of recent BUU studies of nuclear multifragmentation dynamics: Moretto et al [5] recently reported that the head-on collision of two Mo nuclei at typically 60 MeV per nucleon would lead to relatively thin oblate disks (so thin that the nuclear force can reach through width of the disk) which would then cluster as a result of Rayleigh-type instabilities. This remarkable result was soon followed by similar studies by other groups who found conflicting results.…”
