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=⁸Li_gs, ⁸Lin=⁹Li_gs 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=⁹Be_gs 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.

Keywords : Capture reactions; transfer reactions; spectroscopic factors.
