Sensitivity to multi-phonon excitations in heavy-ion fusion reactions
Measured cross sections for the fusion of Ni with Ni, Ge, and Mo targets are analyzed in a coupled-channels approach. The data for the Ni target above 0.1 mb are reproduced by including couplings to the low-lying 2 and 3 states and the mutual and two-phonon excitations of these states. The calculations become more challenging as the fusing nuclei become softer and heavier, and excitations to mu...
متن کاملSignature of smooth transition from sudden to adiabatic states in heavy-ion fusion reactions at deep sub-barrier energies.
We propose a novel extension of the standard coupled-channels framework for heavy-ion reactions in order to analyze fusion reactions at deep-sub-barrier incident energies. This extension simulates a smooth transition between the two-body and the adiabatic one-body states. To this end, we damp gradually the off-diagonal part of the coupling potential, for which the position of the onset of the d...
متن کاملExcitation of nuclear anharmonic vibrations in heavy-ion fusion reactions
We discuss the e ects of multi-phonon excitations on heavy-ion fusion reactions at energies near and below the Coulomb barrier, focusing especially on the role of anharmonicities. We carry out a systematic study of those e ects on the excitation function of the fusion cross section and on the fusion barrier distribution, by using the vibrational limit of the interacting boson model. We also ana...
متن کاملStopping in Relativistic Heavy Ion Reactions From SIS to RHIC
The status of stopping in heavy ion reactions is reviewed by comparing available data in pp, pA and AA systems over the energy regime √ sNN ≈ 2.5− 130 GeV. The data consist of average rapidity losses, anti-proton over proton ratios, and net-baryon values at mid-rapidity. The overall features of nuclear stopping are reasonbly well described by simple extrapolations of pp, and pA collisions to AA.
متن کاملHadronization in Heavy-ion Reactions
We present a model of fast hadronization of constituent quark matter in relativistic heavy ion collisions based on rate equations and capture cross sections in non-relativistic potential. We utilize a thermodynamically consistent approach with a non-ideal equation of state including correlation terms based on string phenomenology. We investigate strange and non-strange particle ratios observed ...
