GUIMARAES, V et al. Transfer reactions in the investigation of light-nuclei nucleosynthesis. Rev. mex. fis. [online]. 2008, vol.54, suppl.3, pp.63-68. ISSN 0035-001X.

Cross sections for the 6Li(p,γ)7 Be, 7Li(n,γ)8 Li 8Li(n,γ)9 Li and 8Li(p,γ)9 Be capture reactions have been investigated in the framework of the potential model. The main ingredients of the potential model are the potentials used to generate the continuum and bound-state wave functions and spectroscopic factors of the corresponding bound systems. The spectroscopic factors for the 7Lin=8Ligs, 8Lin=9Ligs bound systems were obtained from a FR-DWBA analysis of neutron transfer reactions induced by 8Li radioactive beam on a 9Be target, while spetroscopic factor for the 8Lip=9Begs bound system were obained from a proton transfer reaction. From the obtained capture reaction cross section, reaction rate for the 8Li(n, γ)9Li and 8Li(p, γ)9Be direct neutron and proton capture were determined and compared with other experimental and calculated values.

Palavras-chave : Capture reactions; transfer reactions; spectroscopic factors.
