质子滴线核17F+58Ni在近垒能区的准弹性散射角分布研究
Study on Quasi-elastic Scattering Angular Distribution of Proton Drip-line Nucleus 17F+58Ni at Energy near Coulomb Barrier
摘要
Abstract
17F is a proton drip-line nucleus,which is an unstable weakly bound nucleus.As a proton drip-line nucleus,the proton separation energy of 17F is merely 601 keV.Its structure can be described as 16O+p.The first excited state of 17F was predicted to present a proton-halo structure.The experimental study of 17F is of great significance for further understanding the reaction mechanism of proton-rich weakly bound nuclei.In this work,the reaction mechanisms of 17F+58Ni at the energy near the Coulomb barrier were investigated with the beam provided by the RIBLL1 terminal in Lanzhou.17F and 16O were completely identified by using a self-designed telescope array consisting of ionization chambers and silicon detectors.The quasi-elastic scattering angular distribution of 17F+58Ni at Elab=63.0 MeV was obtained.Further theoretical calculations were carried out by continuum-discretized coupled-channels method,which can reproduce the experimental data reasonably well.Moreover,there is no significance difference between the calculations with and without couplings to the continuum states,indicating that the coupling effect on the continuum states of 17F is not strong for the elastic scattering channel.关键词
