Abstract:

A new constraint of clustering for the AMD calculation is proposed. This constraint yields a significant improvement in the investigation of the cluster structure using AMD, which sometimes meets with difficulty in producing certain specific cluster configurations. The usefulness of this constraint is verified by applying it to the the study of the K^π= 0₃⁺ band of ²⁰Ne, which has been conjectured to have 2α-¹²C structure. This band is not easy to construct with AMD. We show that the constraint in the AMD + GCM calculation is effective for the purpose of obtaining the K^π= 0₃⁺ band, which contains the 2α-¹²C structure as an important component.
