利用具有Gogny有效相互作用的反对称分子动力学方法，研究了24mg的低洼谱和e2跃迁速率。在光谱与观测结果比较的基础上，强调了γ变形在正宇称态和负宇称态的重要性。在得到的7个带中，Kπ= 2+、0−和3−带是三轴形变的，并且发现包含γ变形的自由度是描述它们的必要条件。
By using the antisymmetrized molecular dynamics with Gogny effective interaction, the low-lying spectrum and theE2 transition rates of24Mg are studied. On the basis of the comparison of the spectrum with observations, the importance of γ deformation in both positive- and negative-parity states is emphasized. Among the seven bands obtained,Kπ= 2+, 0−and 3−bands are triaxial deformed, and the inclusion of the degree of freedom of γ deformation is found to be essential to describe them.
