论文摘要
背景：最近，Bijker等。 [物理。莱特牧师。 122，162501（2019）]通过假设具有D'3H对称性的三角形核形状来解释13C的旋转振动光谱。目的：这项工作的目的是基于微观核模型测试13C的形状和对称性，而不假设核形状。方法：我们将实时演变方法应用于13C。通过使用簇的运动方程，该模型描述了3alpha+n系统，而无需任何对称性假设。结果：REM比以前的群集模型研究更准确地描述了低洼状态。波函数的分析表明，地面带具有近似的三角形对称性，而激发带偏离了它。结论：这项工作证实了地面带具有三个α颗粒的三角形布置的固有结构。
Background : Recently, Bijker et al. [Phys. Rev. Lett. 122, 162501 (2019)] explained the rotation-vibration spectrum of 13C by assuming triangular nuclear shape with D'3h symmetry. Purpose : The purpose of this work is to test the shape and symmetry of 13C based on a microscopic nuclear model without assumption of nuclear shape. Method : We have applied the real-time evolution method to 13C. By using the equation-of-motion of clusters, the model describes the 3alpha+n system without any assumption of symmetry. Results : REM described the low-lying states more accurately than the previous cluster model studies. The analysis of the wave functions showed that the ground band has approximate triangular symmetry, while the excited bands deviate from it. Conclusion : This work confirmed that the ground band has the intrinsic structure with the triangular arrangement of three alpha particles.
