标题： Ab initio computation of charge densities for Sn and Xe isotopes

摘要： 我们首次对锡同位素线以外的开放壳核进行了从头计算，重点研究了氙同位素以及双幻数锡同位素。 我们表明，即使对于中等硬度的相互作用，也有可能获得有意义的预测，而NNLOsat手征相互作用预测的半径和电荷密度分布接近实验结果。 我们随后对${}^{100}$Sn做出了新的预测。 这为在当前从头计算质量域极限处对奇异电荷密度分布的从头研究铺平了道路，此时实验数据正在逐渐出现。 本研究填补了从头方法可达到的最大同位素与电子散射实验可触及的最小奇异核之间的差距。 显示英文摘要

摘要： We present the first ab initio calculations for open-shell nuclei past the tin isotopic line, focusing on Xe isotopes as well as doubly-magic Sn isotopes. We show that, even for moderately hard interactions, it is possible to obtain meaningful predictions and that the NNLOsat chiral interaction predicts radii and charge density distributions close to the experiment. We then make a new prediction for ${}^{100}$Sn. This paves the way for ab initio studies of exotic charge density distributions at the limit of the present ab initio mass domain, where experimental data is becoming available. The present study closes the gap between the largest isotopes reachable by ab initio methods and the smallest exotic nuclei accessible to electron scattering experiments.
