用实时演化方法研究~(13)C的形状

Shape of 13C studied by the real-time evolution method

S. Shin, B. Zhou, M. Kimura

摘要:

背景:最近,Bijker等人[Phys. Rev. Lett. 122,162501(2019)]通过假设具有D '3 h对称性的三角形核形状解释了13 C的旋转振动光谱。目的:本工作的目的是在不假设核形状的情况下,基于微观核模型测试13 C的形状和对称性。方法:将实时进化方法应用于13 C。该模型利用团簇的运动方程描述了3alpha+n系统,而没有任何对称性假设。结果:快速眼动模型比以往的集群模型更准确地描述了低水平状态。波函数分析表明,基态带近似三角对称,而激发带偏离三角对称.结论:本工作证实了基态带具有三个α粒子三角形排列的本征结构.

英文摘要:

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.
