论文摘要
质子密度分布的均方根均方根$^{16-24} $ o从碳靶的较换横截面$ \ sim $ \ sim $ 900 $ a $ a $ meV的测量中得出。壳封闭的烙印在$ n $ = 14中，16个反映在其质子半径的局部最小值中，这为引起张量的张量相互作用提供了证据。通过手性nnlo $ _ {\ mathrm {sat}} $相互作用的从头开始计算，尽管皮肤厚度预测是挑战的，但使用手性nnlo $ _ {\ mathrm {sat}} $一致。 Shell模型预测与数据非常吻合。
The root mean square radii of the proton density distribution in $^{16-24}$O derived from measurements of charge changing cross sections with a carbon target at $\sim$900$A$ MeV together with the matter radii portray thick neutron skin for $^{22 - 24}$O despite $^{22,24}$O being doubly magic. Imprints of the shell closures at $N$ = 14 and 16 are reflected in local minima of their proton radii that provide evidence for the tensor interaction causing them. The radii agree with it ab initio calculations employing the chiral NNLO$_{\mathrm{sat}}$ interaction, though skin thickness predictions are challenged. Shell model predictions agree well with the data.
