Abstract Starting from chiral two-nucleon (2NF) and chiral three-nucleon (3NF) potentials, we present a detailed study of 17Ne, a Borromean system, with the Gamow shell model which can capture continuum effects. More precisely, we take advantage of the normal-ordering approach to include the 3NF and the Berggren representation to treat bound, resonant and continuum states on equal footing in a complex-momentum plane. In our framework, 3NF is essential to reproduce the Borromean structure of 17Ne, while the continuum is more crucial for the halo property of the nucleus. The two-proton halo structure is demonstrated by calculating the valence proton density and correlation density. The astrophysically interesting 3 / 2 − excited state has its energy above the threshold of the proton emission, and therefore the two-proton decay should be expected from the state.

Borromean 系统中的连续介质和三核子力：17Ne 情况

摘要 从手性二核子 (2NF) 和手性三核子 (3NF) 势开始，我们详细研究了 17Ne，一种 Borromean 系统，以及可以捕获连续效应的 Gamow 壳模型。更准确地说，我们利用正常排序方法来包括 3NF 和 Berggren 表示，以在复动量平面中平等地处理束缚态、共振态和连续态。在我们的框架中，3NF 对于重现 17Ne 的 Borromean 结构至关重要，而连续体对于原子核的晕圈特性更为关键。通过计算价质子密度和相关密度来证明双质子晕结构。天体物理学上有趣的 3 / 2 - 激发态的能量高于质子发射阈值，
