Abstract:
We propose a simplified model to directly take into account the contribution of the tensor interaction (SMT) for light nuclei by extending the α-cluster model. In ⁸Be, the energy curve with respect to the relative distance between the two ⁴He clusters suggests that the cluster structure persists even though the tensor interaction contributes strongly. In addition to SMT, a simplified method to take into account the strong spin-orbit contributions is introduced and the coupling effects of these two models is shown to be important in ¹²C, in contrast to ⁸Be.
