Multinucleon transfer inO16,18,F19+Pb208reactions at energies near the fusion barrier

Fusion at near-barrier energies within the quantum diffusion ap- proach

Within the quantum diffusion approach, the role of neutron transfer in fusion (capture) reactions with tightly and weakly bound nuclei is discussed. The breakup process is analyzed. New methods for the study of the breakup probability are suggested.

Transfer at sub-barrier energies and its role in understanding the suppression of fusion

Fusion cross section measurements in nuclear reactions of heavy nuclei consistently fall below model predictions at energies both well below and above the fusion barrier. Understanding the physical mechanisms leading to this fusion suppression has been one of the major challenges in nuclear reaction physics [6, 7, 1]. It is crucial for a consistent understanding of nuclear reactions involving b...

Semi-classical Characters and Optical Model Description of Heavy Ion Scattering, Direct Reactions, and Fusion at Near-barrier Energies

An approach is proposed to calculate the direct reaction (DR) and fusion probabilities for heavy ion collisions at near-Coulomb-barrier energies as functions of the distance of closest approach D within the framework of the optical model that introduces two types of imaginary potentials, DR and fusion. The probabilities are calculated by using partial DR and fusion cross sections, together with...

Validity of the linear coupling approximation in heavy-ion fusion reactions at sub barrier energies

The role of higher order coupling of surface vibrations to the relative motion in heavyion fusion reactions at near-barrier energies is investigated. The coupled channels equations are solved to all orders, and also in the linear and the quadratic coupling approximations. Taking Ni + Zr reactions as examples, it is shown that all order couplings lead to considerably improved agreement with the ...
