Recent experimental results on particles-gamma coincidence measurements on the systems C-12 + Ni-64 and Cl-35 + Ni-64 at about 8MeV/nucleon are interpreted as due to the effect of a Dipole pre-equilibrium emission produced during the damping of the proton-neutron relative collective motion in very deformed intermediate systems formed in the first instants of the collision. The pre-equilibrium effects are evaluated through semiclassic kinetic theories and through modified statistical approach to include non-stationary effects in Fusion processes, Massive Transfer reactions (in the C-12 + Ni-64 system) and in Binary Dissipative reactions (in the Cl-35 + Ni-64 system). In particular the study performed on the dipole molecular component allows to establish a link between the above phenomenon and the charge and mass transfer process in quasi-peripheral reactions.

Abstract
Recent experimental results on particles-gamma coincidence measurements on the systems C-12 + Ni-64 and Cl-35 + Ni-64 at about 8MeV/nucleon are interpreted as due to the effect of a Dipole pre-equilibrium emission produced during the damping of the proton-neutron relative collective motion in very deformed intermediate systems formed in the first instants of the collision. The pre-equilibrium effects are evaluated through semiclassic kinetic theories and through modified statistical approach to include non-stationary effects in Fusion processes, Massive Transfer reactions (in the C-12 + Ni-64 system) and in Binary Dissipative reactions (in the Cl-35 + Ni-64 system). In particular the study performed on the dipole molecular component allows to establish a link between the above phenomenon and the charge and mass transfer process in quasi-peripheral reactions.File | Dimensione | Formato | |
