我们提出了一个系统的研究少核子系统和轻核使用目前的LENPIC相互作用包括半局域动量空间正则化的两个和三个核子力的第三手征级（N$^2$LO）。利用坐标空间正则化的相互作用，从核子-氘核弹性散射中的束缚能和微分截面极小值确定了进入三体力的两个低能常数.预测选定的可观测的弹性核子-氘散射和氘分裂反应，为属性的$A=3$和$A=4$的核，和光谱的$p$壳核高达$A = 16$。进行了全面的误差分析，包括核谱的相关截断不确定度的估计。所得到的预测一般被认为是同意与实验数据的误差。类似的坐标空间正则化的手征相互作用在相同的顺序，观察到一个系统的较重的核的过束缚，它设置在$A \sim 10$和增加与$A$。
We present a systematic investigation of few-nucleon systems and light nuclei using the current LENPIC interactions comprising semilocal momentum-space regularized two- and three-nucleon forces up to third chiral order (N$^2$LO). Following our earlier study utilizing the coordinate-space regularized interactions, the two low-energy constants entering the three-body force are determined from the triton binding energy and the differential cross section minimum in elastic nucleon-deuteron scattering. Predictions are made for selected observables in elastic nucleon-deuteron scattering and in the deuteron breakup reactions, for properties of the $A=3$ and $A=4$ nuclei, and for spectra of $p$-shell nuclei up to $A = 16$. A comprehensive error analysis is performed including an estimation of correlated truncation uncertainties for nuclear spectra. The obtained predictions are generally found to agree with experimental data within errors. Similar to the coordinate-space regularized chiral interactions at the same order, a systematic overbinding of heavier nuclei is observed, which sets in for $A \sim 10$ and increases with $A$.
