论文摘要
具有同胞0的钙-40核的100多个激发态被分类为固有的四面体结构的旋转振动带。几乎所有观察到的状态都可以容纳8 MEV，以及8 MEV以上的许多高旋转状态。频段与氧气16的分类状态具有一定的相似性，但是相对于E模式和F模式频率，A模式振动频率低于氧气-16。先前确定的旋转带直至旋转16，而20 MEV高于20 MEV的旋转频带在此统一为较小数量的四面体带。
More than 100 excited states of the Calcium-40 nucleus, with isospin 0, are classified into rotational-vibrational bands of an intrinsic tetrahedral structure. Almost all observed states below 8 MeV can be accommodated, as well as many high-spin states above 8 MeV. The bands have some similarity to those classifying states of Oxygen-16, but the A-mode vibrational frequency is lower relative to the E-mode and F-mode frequencies than in Oxygen-16. Previously identified rotational bands up to spin 16 and energy above 20 MeV are unified here into a smaller number of tetrahedral bands.
