论文摘要
我们解决了无限核物质的饱和行为与基于最先进的手性二和三核力力的有限核的描述之间的联系。我们观察到，已经发现的两种和三个核子相互作用（在N2LO和N3LO上）可以预测广泛的有限核（从P壳核（从P-Shell核到镍等底座）无法饱和的无限无限核电。另一方面，已经表明，手性三个核子相互作用的CD和CE耦合的拟合还包括核物质饱和度的约束，除了通常情况下，Triton结合能，中等质量的核源是水平的，并且它们的半径在symatematic上太大。我们讨论了这种明显的不一致性，并对各种情况进行测试计算，以阐明问题。
We address the connection between the saturating behavior of infinite nuclear matter and the description of finite nuclei based on state-of-the-art chiral two- and three-nucleon forces. We observe that chiral two- and three-nucleon interactions (at N2LO and at N3LO) which have been found to predict realistic binding energies and radii for a wide range of finite nuclei (from p-shell nuclei up to nickel isotopes) are unable to saturate infinite nuclear matter. On the other hand, it has been shown that, when the fits of the cD and cE couplings of the chiral three-nucleon interactions include the constraint of nuclear matter saturation in addition to, as is typically the case, the triton binding energy, medium-mass nuclei are underbound and their radii are sytematically too large. We discuss this apparent inconsistency and perform test calculations for various scenarios to shed light on the issue.
