Microscopic analysis based on the g-matrix folding model for reactions involving unstable nuclei

 Microscopic understanding of optical potentials for nucleon-nucleus and nucleus-nucleus scattering is a long-standing issue in nuclear reaction theory. The optical potentials are the key to calculate the elastic scattering and reactions, including higher-order processes. The g matrix folding model yields the reliable optical potential based on the nucleon-nucleon interaction, and well describes various scattering of stable nuclei. However, the folding model does not work well for the scattering of unstable nuclei, due to the lack of the breakup effects.

 In the previous work, we have constructed microscopic optical potential including breakup effects based on the Glauber model. The constructed optical potential is called the Eikonal potential. For deuteron scattering, the validity of the Eikonal potential has been investigated from the comparison with results of the continuum-discretized coupled channels method (CDCC). Indeed, the calculated cross sections with the Eikonal potential reproduce well those with CDCC.

 In this study, we apply Eikonal potential to reactions of one or two neutron halo nuclei, and investigate the validity by comparing with results of CDCC. In this conference, we will report these results and discuss applicability to breakup reactions.
