斜轴推转协变密度泛函理论在核磁和反磁转动中的研究进展

Progress on tilted axis cranking covariant density functional theory for nuclear magnetic and antimagnetic rotation

J. Meng, J. Peng, S. Q. Zhang, P. W. Zhao

摘要:

磁转动和反磁转动是在弱形变或近球形核中观察到的奇异转动现象,分别用剪切机制和双剪切机制解释。自观测以来,磁旋转和反磁旋转现象主要是在基于对加四极模型的斜轴曲柄框架下研究的。近几十年来,协变密度泛函理论及其推广已被证明成功地描述了一系列核基态和激发态性质,包括结合能、半径、单粒子谱、共振态、晕现象、磁矩、磁转动、低激发态、形状相变、集体转动和振动,本文主要介绍斜轴推转协变密度泛函理论及其在磁旋转和反磁旋转现象中的应用。

英文摘要:

Magnetic rotation and antimagnetic rotation are exotic rotational phenomena observed in weakly deformed or near-spherical nuclei, which are respectivelyinterpreted in terms of the shears mecha-nism and two shearslike mechanism. Since their observations, magnetic rotation and antimagnetic rotation phenomena have been mainly investigated in the framework of tilted axis cranking based on the pairing plus quadrupole model. For the last decades, the covariant density functional theory and its extension have been proved to be successful in describing series of nuclear ground-states and excited states properties, including the binding energies, radii, single-particle spectra, resonance states, halo phenomena, magnetic moments, magnetic rotation, low-lying excitations, shape phase transitions, collective rotation and vibrations, etc. This review will mainly focus on the tilted axis cranking covariant density functional theory and its application for the magnetic rotation and antimagnetic rotation phenomena.
