标题： Gamow shell model study of the 17Ne(p, p) reaction and of isospin symmetry breaking in 18Na

摘要： 未结合的原子核18Na，在19Mg的顺序衰变中作为中间原子核，位于质子滴线之外。 我们采用耦合通道伽莫夫壳模型（GSM-CC）来研究18Na的性质，以及17Ne(p, p)的散射截面。 GSM-CC将原子核视为开放量子系统，并为研究核结构和反应散射截面提供了一个统一的框架。 我们的计算再现了18Na低能态的能量和部分衰变宽度，以及17Ne(p, p)的散射截面。 此外，镜像原子核18N也得到了描述。 由于扩展的s1/2分波，由库仑相互作用和连续谱耦合引起的同位旋对称性破缺在我们对18Na和18N性质的描述中明显体现出来。 对18Na/18N对中的同位旋对称性破缺与镜像对16F/16N中出现的同位旋对称性破缺进行了比较，分析了它们的相似性和差异性。 显示英文摘要

摘要： The unbound nucleus 18Na, acting as an intermediate nucleus in the sequential decay of 19Mg, is situated beyond the proton drip line. We employ the coupled-channel Gamow shell model (GSM-CC) to investigate the properties of 18Na, as well as the 17Ne(p, p) cross section. GSM-CC treats the nucleus as an open quantum system and provides a unified framework for studying both nuclear structure and reaction cross sections. Our calculations reproduce the energies and partial decay widths of low-lying states in 18Na, as well as the 17Ne(p, p) cross section. Additionally, the mirror nucleus 18N is also described. The isospin symmetry breaking induced by the Coulomb interaction and continuum coupling is clearly obtained in our description of 18Na and 18N properties, arising from the extended s1/2 partial wave. The isospin symmetry breaking in the 18Na/18N pair is compared to that occurring in the mirror pair 16F/16N, whereby similarities and differences are analyzed.
