The role of dynamics in the fusion of two heavy nuclei
Nuovo Cimento Della Societa Italiana Di Fisica A-nuclei Particles and Fields(2008)
Abstract
Summary We use a simple parametrization of the interaction potential between two heavy ions to calculate static fusion barriers and
the limit of fusion. A phenomenological dynamical model is presented which allows us to reproduce the fusion excitation functions
of a large number of systems measured experimentally. The role of the dynamics on the fusion process is investigated in details
and it is shown that the dynamical fusion barriers can be, in some cases, different from the static ones. The difference between
them, called the dynamical energy surplus, is studied as a function of different variables and is shown to have a great influence
on the fusion cross-sections.
