摘要
To explain the experimental observation that the fusion cross-section of a proton-halo nucleus with a heavy target nucleus is not enhanced as expected,the shielding hypothesis was proposed,where the proton-halo nucleus is polarized and the valence proton shielded by the core.In the frame of the improved quantum molecular dynamics model,the fusion reaction 17F on 208Pb around the Coulomb barrier is simulated.The existence of the shielding effect is verified by the microscopic dynamics simulations.Its influence on the effective interaction potential is also investigated.
