用简单折叠核-物质分布得到的光势分析了$ensuremath{alpha}$粒子的弹性散射。利用电荷分布参数提取了$^{208}mathrm{Pb}$中子物质半径。将所得结果${r}_{mathm {nm}}=5.75ifmmodepmelse extpmfi{}0.09$ fm与其他测定结果和一些理论计算结果进行了比较。
The elastic scattering of $ensuremath{alpha}$ particles is analyzed with an optical potential obtained by a simple folding of the nuclear-matter distribution with an $ensuremath{alpha}$-nucleon interaction. The $^{208}mathrm{Pb}$ neutron-matter radius is extracted using the charge-distribution parameters. The result ${r}_{mathrm{nm}}=5.75ifmmodepmelse extpmfi{}0.09$ fm is compared with other determinations and some theoretical calculations.
