自旋为零时的核四面体构型

Nuclear tetrahedral configurations at spin zero

Krzysztof Zberecki, Paul-Henri Heenen, Piotr Magierski

摘要:

本文用Skyrme-HFBCS方法和生成坐标法研究了自旋为零时稳定四面体形变存在的可能性。研究仅限于核的四面体模式已被预测为有利于非自洽模型的基础上。我们的研究结果表明,一个明确的识别四面体变形是不可能的,因为他们是强烈的轴向八极模混合。然而,与四面体模相关的激发能在本研究中包括的所有核中系统地低于轴向八极模。

英文摘要:

The possibility of the existence of stable tetrahedral deformations at spin zero is investigated using the Skyrme-HFBCS approach and the generator coordinate method (GCM). The study is limited to nuclei in which the tetrahedral mode has been predicted to be favored on the basis of non self-consistent models. Our results indicate that a clear identification of tetrahedral deformations is unlikely as they are strongly mixed with the axial octupole mode. However, the excitation energies related to the tetrahedral mode are systematically lower than those of the axial octupole mode in all the nuclei included in this study.
