摘要
理论和实验结果都表明17F的第一激发态有质子晕存在 .用相对论平均场理论和Eikonal近似研究了质子晕核17F的第一激发态的电子弹性散射过程 .计算了17F的第一激发态的电荷形状因子 ,并与16 O和19F的结果进行了对比和讨论 .结果显示质子晕的存在会使中等转移动量的电荷形状因子产生明显的变化 ,并且使低转移动量的电荷形状因子趋于降低 .这说明电子散射对质子晕的存在是非常敏感的 ,表明可以用电子散射对奇特核的质子晕结构进行更精细的研究 .
Both theoretical calculations and experimental observations show that there exists proton halo in the first excited state (1/2)+ of 17F. The elastic electron scattering process on the first excited state of 17F is studied with the RMF model and Eikonal approximation. The charge form factor is calculated and compared with those of 16O and 19F. The results show that the existence of the proton halo can lead to an obvious change of the form factors in the range of low and moderate momentum transfer. This indicates that elastic electron-nucleus scattering can be an effective tool for a refined study of the proton-halo structure of proton-rich nuclei.
