Low‑lying resonances in 17O and 29,31F with complex momentum representation approach

We explored the viability of the complex momentum representation (CMR) approach coupled with given potentials. A Woods-Saxon potential based on the Koning-Delaroche optical model and constrained by the experimental one-neutron separation energy was used for 17O, and a standard spherical potential by A. Bohr was adopted for 29F and 31F. We successfully achieved a reasonable prediction for the level-energies of both the bound states and low-lying resonant states. This dataset contains the positions of states of 17O and 29,31F in complex momentum plane and complex energy plane. And a set of accuracy data produced by varying grid points number and truncations of integration in the momentum and coordinate space is also included. The dataset is freely available and can be utilized as a sample for CMR study. Details can be found in the relevant article.

本研究探究了结合给定势场的复动量表象（Complex Momentum Representation, CMR）方法的可行性。针对17O核，我们采用了基于Koning-Delaroche光学模型且受实验单中子分离能约束的Woods-Saxon势场；针对29F与31F核，则采用了A. Bohr提出的标准球形势场。本研究成功对束缚态与低激发共振态的能级作出了合理预测。本数据集包含17O、29F与31F的核态在复动量平面与复能量平面中的坐标位置。此外，数据集还包含通过改变动量空间与坐标空间的格点数目以及积分截断参数所得到的一系列精度验证数据。本数据集可免费获取，可作为复动量表象研究的示例数据集使用，详细信息可参阅相关研究论文。
