“…In many calculations, the barrier height is considered to be reduced by the halo neutron, based on the folding picture. 22), 23) There are predictions expecting both the enhancement of the fusion cross section 62), 63) and the hindrance 64), 65) by the coupling to the continuum states. On the other hand, the importance of the coupling with transfer channel has been stressed.…”

Theoretical descriptions for the reactions of halo nuclei are reviewed. Depending on the projectile incident energy as well as the reaction mechanisms, several theoretical frameworks have been developed for the reactions of halo nuclei. They are presented in a systematic way to elucidate their mutual relationship. The Glauber's multiple scattering theory is adequate to describe the high energy reactions. The theory is applied to the integrated cross sections such as interaction and neutron removal cross sections, and also to the momentum distribution of the fragment nucleus. A few-body direct reaction model is appropriate to describe the medium energy reactions. This is applied to the elastic scattering of halo nuclei and to construct their optical potentials. For the Coulomb breakup reactions, theoretical treatments are developed in the time-dependent Schödinger equation with and without the perturbation approximation. A direct approach to solve the equation is applied to analyze the postacceleration mechanism in the Coulomb breakup process. Finally a fusion reaction of the halo nuclei is discussed with a three-body model.

“…Concerning effects of the neutron halo on the nuclear reactions, a theoretical study has been performed with various models and has put rather different predictions on the fusion cross section [1][2][3][4][5][6][7][8], while the experimental study has become feasible only recently [9][10][11]. Thus, the effect of the neutron halo has not yet been clarified.…”

The fusion is studied for reactions between a stable and an unstable nuclei with neutron skin. The reactions and are taken as examples, and the three-dimensional time-dependent Hartree - Fock method with the full Skyrme interaction is used. It is shown that, in such reactions, the nucleon transfer is enhanced enormously for both protons and neutrons. As a whole, it is seen that the neutron skin does not enhance the fusion cross section in the calculations made so far.

Quasi-free scattering in inverse kinematics as a tool to unveil the structure of nuclei

2021

Quasi-free scattering of electrons and protons has been extensively utilized in the past to study the single-particle structure of nuclei, clustering in light nuclei, and short-range correlated nucleon–nucleon pairs in nuclei. Recently, this approach has been applied in inverse kinematics using hydrogen targets. The characteristic features of this reaction and the experimental challenges and advantages of inverse-kinematics experiments are summarized. The applicability to radioactive beams opens a large research potential to study a variety of properties of neutron-to-proton asymmetric nuclei. Applications of quasi-free scattering in inverse kinematics and its potential are reviewed based on recent and ongoing research programs at different accelerator facilities worldwide.
