一个微观团簇模型被应用于，和系统，以研究团簇在基态和径向激发下的运动。在微观计算中，采用距离坐标的生成坐标法，得到了建立在基态上的大振幅模的激发态。利用微观团簇模型的输入，如范数核和能量期望值，构造了一个集体模型来描述这些态的团簇运动。此外，通过引入虚部坐标，对团簇模型进行了扩展，以考虑动力学效应对集体质量的影响。集体模型得到的集体波函数被认为是在合理的协议与发电机坐标方法的能量，均方根半径，和振幅函数的结果。
A microscopiccluster model was applied to, andsystems to investigate cluster motion in the ground state and radial excitation. In the microscopic calculation ofandusing the generator coordinate method with the coordinateof thedistance, excited states were obtained as the large-amplitude mode built on the ground state. A collective model was constructed to describe the cluster motion of these states by utilizing inputs from the microscopic cluster model such as the norm kernel and energy expectation values. Furthermore, the cluster model was extended by introducing the imaginary part of the coordinateto incorporate the dynamical effects on the collective mass. The collective wave function obtained with the collective model was found to be in reasonable agreement with the results of the generator coordinate method for energies, root-mean-square radii, and amplitude functions.
