Light charged particle emission in heavy-ion reactions — What have we learnt?

Abstract

Light charged particles emitted in heavy-ion induced reactions, their spectra and angular distributions measured over a range of energies, carry the signature of the underlying reaction mechanisms. Analysis of data of light charged particles, both inclusive and exclusive measured in coincidence with gamma rays, fission products, evaporation residues have yielded interesting results which bring out the influence of nuclear structure, nuclear mean field and dynamics on the emission of these particles.

Preequilibrium neutron emission in heavy ion reaction: Mean field effect and multiple emission

“…In heavy ion reaction at several tens of MeV/u, along with the PEQ emissions, a few more processes such as incomplete fusion, deep inelastic collisions, and breakup fusions also play dominant roles over the former processes depending upon the particle energy [5][6][7][8]. In heavy ion reaction, the relaxation process is influenced by the nuclear mean field as well as the nucleon-nucleon interaction [9]. At a projectile energy range of ∼10-30 MeV/u, both these processes play important roles and govern the yield and energy-angle distribution of the emitted particles.…”
