摘要:
通过对玻尔哈密顿量在SO(5)基上的精确数值对角化,在几何框架内对大变形转子核中的声子和多声子激发进行了详细的定量预测.动态伽马变形被发现显着影响的预测,通过其耦合到旋转运动。刚性三轴变形开始的基本签名也得到了。
英文摘要:
Detailed quantitative predictions are obtained for phonon and multiphonon excitations in well-deformed rotor nuclei within the geometric framework, by exact numerical diagonalization of the Bohr Hamiltonian in an SO(5) basis. Dynamical gamma deformation is found to significantly influence the predictions through its coupling to the rotational motion. Basic signatures for the onset of rigid triaxial deformation are also obtained.
