论文摘要
我们提出了经过锡同位素线的开放壳核的第一个从头算计算，重点是XE同位素以及双粘性SN同位素。我们表明，即使对于中等硬的相互作用，也有可能获得有意义的预测，并且NNLOSAT手性相互作用可以预测半径和电荷密度分布接近实验。然后，我们对$ {}^{100} $ sn进行了一个新预测。这为从头开始质量域的限制的外来电荷密度分布进行了从头开始研究铺平了道路，在该质量质量域的范围内，实验数据正在可用。本研究缩小了可从头算方法与电子散射实验可访问的最小的外来核达到的最大同位素之间的差距。
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.
