摘要：

This work briefly introduces our recent studies on reactions induced by proton drip-line nuclei, B-8 and F-17, at energies around the Coulomb barrier. Using detector arrays with large solid-angle coverage, the complete kinematics measurements were performed for systems of B-8+Sn-120 and F-17+Ni-58. For the B-8+Sn-120, the coincident measurement of the breakup fragments was achieved for the first time for a proton-halo nuclear system. The correlations between the breakup fragments reveal that the prompt breakup occurring on the outgoing trajectory dominates the breakup dynamics of B-8. For F-17+Ni-58, the complete reaction channel information, such as quasi-elastic scattering, breakup and total fusion, was derived for the first time. An enhancement of the fusion cross section of F-17+Ni-58 was observed at the energy below the Coulomb barrier. Theoretical calculations indicate that this phenomenon is mainly due to the couplings to the continuum states. Moreover, different direct reaction dynamics were found in B-8 and F-17 systems, suggesting the influence of proton-halo structure on the reaction dynamics.
