含时平均场的能量与动力学

Shapes and Dynamics from the Time-Dependent Mean Field

P. D. Stevenson, P. M. Goddard, A. Rios

摘要:

用潜在的形状自由度来解释观察到的性质是理解原子核的一个公认的棱镜。自洽平均场模型提供了一种工具来理解核形状,以及它们与其他核性质和可观测量的联系。我们提出的例子,如何依赖于时间的平均场方法的扩展,可以特别是用来阐明核形状的属性,特别是在巨大的共振变形核基态,并在动态高度变形裂变异构体。在第一种情况下示出了$^{28}$ Si的示例计算,在后一种情况下示出了$^{240}$ Pu的示例计算。

英文摘要:

Explaining observed properties in terms of underlying shape degrees of freedom is a well--established prism with which to understand atomic nuclei. Self--consistent mean--field models provide one tool to understand nuclear shapes, and their link to other nuclear properties and observables. We present examples of how the time--dependent extension of the mean--field approach can be used in particular to shed light on nuclear shape properties, particularly looking at the giant resonances built on deformed nuclear ground states, and at dynamics in highly-deformed fission isomers. Example calculations are shown of $^{28}$Si in the first case, and $^{240}$Pu in the latter case.
