A full three-dimensional angular momentum projection on top of a triaxial relativistic mean-field calculation is implemented for the first time. The underlying Lagrangian is a point coupling model and pairing correlations are taken into account by a monopole force. This method is applied for the low-lying excited states in 24Mg. Good agreement with the experimental data is found for the ground state properties. A minimum in the potential energy surface for the 2+ state, with β≈ 0.55, γ≈ 10°, is used as the basis to investigate the rotational energyspectrum as well as the corresponding B(E2) transition probabilities as compared to the available data.

美国教育家帕尔默在著作《教学勇气——漫步教师心灵》中提出“为何教师会失去心灵”“如何重新找回教师心灵”的问题。怎样提升自己的修养和提升自己的幸福感成了教育工作者当下热烈讨论的问题。帕尔默的回答是教师的自身认同和自我完善,马丁纳博士的答案是自我接纳。佛说:物随心转,境由心造,烦恼皆由心生。其实他们说的都是一个意思,一个人有什么样的精神面貌状态就会产生什么样的生活现实。我想师德修炼应该从“心”开始。
