Nuclear jets in heavy-ion collisions

Abstract: Head-on collisions between nuclei of different size at Fermi energies may give rise to extremely deformed dynamical regimes and patterns. Those latter, may suddenly turn into a stream of nuclear clusters, resembling collimated jets. Because the underlying instabilities are inadequately described by usual modelling approaches based on equilibrium approximations, this mechanism resulted rather unnoticed, even though it should be frequently registered in experiments. We employ the Boltzmann-Langevin equation to s… Show more

“…We briefly review some results about head-on 36 Ar+ 58 Ni collisions at Fermi energies, taken as an example of system where nuclear jets were observed both experimentally [14,15] and in the corresponding simulations [13]. With increasing energy, the exit channel moves from mostly fusion (below 25 AMeV) to a large tendency towards the disintegration of the whole system into clusters and light particles (above 90 AMeV).…”

“…They can be evaluated from a first-order analysis of chronology (as an analysis step, fig. 3a illustrates the breakup time of fragments as a function of their size) and cluster correlations [13], restricting to the forward section of the stream of clusters (i.e. the nuclear jet).…”

“…In this energy domain, the BLOB approach can describe the interplay between volume and surface instabilities below nuclear saturation density. As a consequence it is capable of describing extreme situations ranging from multiple breakups in the deep-inelastic regime [156] to the stream of clusters around Fermi energy [157].…”
