摘要: 近库仑位垒能区弱束缚原子核的动力学效应研究是当前热点问题之一.但是由于缺乏对其实验方面的研究,没有系统性的结论,因此需要大力开展实验方面的研究工作.针对质子滴线核17F在中重靶核58Ni上的弹性散射和破裂反应设计了实验装置.根据反应运动学,利用蒙特卡罗程序模拟计算了散射的17F分布,以及破裂产生的16O和质子分布.根据模拟计算,得到了实验装置的参数,包括探测几何效率,覆盖的立体角,反应产物17F、16O和质子的能量沉积和几何关系等.这套装置对16O和质子的符合效率为4.7%±0.1%,这为实验的开展打好了基础.用此装置,将可以在一系列国际大科学装置上开展实验.

Abstract: At energies around Coulomb barrier the study of the dynamic effect of weakly bound nuclei is one of presently hot subjects. However, due to the experimental studies about this field are scarce, especially on the medium-mass target nuclei. It has no systematic conclusion. Therefore, this study needs to be done in the future from the experiment. The experimental setup was designed on basis of elastic scattering and breakup reaction of proton drip-line nucleus 17F on medium-mass 58Ni target. According to the kinematics, the distributions of scattered 17F as well as breakup 16O and proton were simulated by Monte Carlo simulation. The parameters of the experimental setup including geometry efficiency, covered solid angle, energy deposit and geometry relation of production 17F, 16O and proton etc., which were designed on basis of the simulation results. The coincident efficiency of 16O and proton is 4.7%±0.1%. It gives a basis for future experiment. Using this equipment a series of experiments will be developed in the internationally large facilities for science.

Key words: exotic nuclei, elastic scattering, breakup reaction, detector, simulation, coincident efficiency, experimental setup
