摘要:
Clustering is a very important phenomenon,which has been widely studied in nuclear physics.[1-3] The possible clustering formations contain linear chain,octupole,triangle,ring-like and flower-like shapes.[4-6]Clustering structure is more likely to occur in N =Z or their neighboring nuclei and even in the drip-line nuclei.[7-9] In particular,the α clustering structure is known to play a key role in some nuclei,such as B isotopes,[10] 12C,[11] 16O,[12] 20Ne,[13] 28Si,[14] and 40Ca.
