Proton Halo of ⁸B within Direct Fragmentation Model

Abstract

In a recent publication, Phys. Rev. C 63 (2001) 65806, experimental datas on the coulomb dissociation cross sections of ⁸B have been reported. In the present research, a theoretical attempt has been made to explain these results that are based on direct fragmentation model when ⁸B interacts with ¹⁰⁷Ag and ²⁰⁸Pb target nuclei. The symmmetric momentum distribution of the ejected ⁷Be might be due to outcome of both nuclear and coulomb effect for the dissociation of ⁸B.
