Simultaneous analysis of the elastic scattering and breakup channel for the reaction 11 Li + 208 Pb at energies near the Coulomb barrier

Description

We present a detailed analysis of the elastic scattering and breakup channel for the reaction of Li11 on Pb208 at incident laboratory energies of 24.3 and 29.8 MeV, measured at the radioactive ion beam facility of TRIUMF, in Vancouver, Canada. A large yield of Li9 fragments was detected by four charged particle telescopes in a wide angular range. The experimental angular and energy distributions of these Li9 fragments have been compared to coupled-reaction-channel and continuum-discretized coupled-channel calculations. The large production of Li9 fragments at small angles can be explained by considering a direct breakup mechanism, while at medium-large angles a competition between direct breakup and neutron transfer to the continuum of the Pb208 target was observed.
