新发现的${}^{17}$F的第一激发${（1/2）}^{+}$态质子晕[R.莫洛克等人，物理修订信函79，3837（1997）]中的非线性相对论平均场模型。结果表明，该模型在不引入任何特殊参数的情况下，不仅能很好地再现${}^{17}$F的基态性质，而且能很好地再现激发${（1/2）}^{+}$态的质子晕。本文还讨论了邻核${}^{18}$Ne中存在质子晕的可能性。
The newly discovered proton halo in the first excited ${(1/2)}^{+}$ state of ${}^{17}$F [R. Morlock et al., Phys. Rev. Lett. 79, 3837 (1997)] is investigated in the nonlinear relativistic mean-field model. It is shown that this model, without introducing any specifically adjusted parameters, can reproduce well not only the ground state properties of ${}^{17}$F but also the proton halo in the excited ${(1/2)}^{+}$ state. The possibility of the existence of a proton halo in the neighboring nucleus ${}^{18}$Ne is also discussed.
