Density distribution ofLi8and8Band capture reaction at low energy

Abstract

Reaction cross sections of Li8 on stable targets were measured at intermediate energies. With the existing experimental data of interaction cross sections at 790 MeV/nucleon the nucleon density distribution of Li8 was extracted by the use of the modified Glauber model. Meanwhile, the existing data of 8B have been also reanalyzed. Structures of Li8 and 8B were compared through the density. On the basis of dilute surface densities, the discussion of 7Li(n,γ)8Li and 7Be(p,γ)8B capture reactions was performed within the framework of the direct capture reaction mechanism. The calculations agreed quite well with the experimental data as well as other analyses.Received 14 November 2014Revised 10 January 2015DOI:https://doi.org/10.1103/PhysRevC.91.014614©2015 American Physical Society
