We predict the limits of existence of atomic nuclei, the proton and neutron drip lines, from the light through medium-mass regions. Starting from a chiral two- and three-nucleon interaction with good saturation properties, we use the valence-space in-medium similarity renormalization group to calculate ground-state and separation energies from helium to iron, nearly 700 isotopes in total. We use the available experimental data to quantify the theoretical uncertainties for our ab initio calculations towards the drip lines. Where the drip lines are known experimentally, our predictions are consistent within the estimated uncertainty. For the neutron-rich sodium to chromium isotopes, we provide predictions to be tested at rare-isotope beam facilities.

原子核的从头算极限

我们预测了从光到中等质量区域的原子核,质子和中子滴线的存在极限。从具有良好饱和特性的手性两核和三核相互作用开始,我们使用价空间中相似相似性重新归一化组来计算从氦到铁的基态和分离能,总共有近700个同位素。我们使用可用的实验数据来量化我们对滴水线的从头算的理论不确定性。在实验中知道滴水线的地方,我们的预测在估计的不确定性内是一致的。对于富含中子的钠到铬同位素,我们提供了在稀有同位素射束设施中要进行测试的预测。
