A tentative plan to prepare new clusters by self-assembly of C36 clusters in gas-phase is given in this paper. The growth process of the carbon clusters under a real He atmosphere is simulated by molecular dynamics method. We find that the ambient temperature is the key factor to affect the final structures of the n ew clusters: from 1000 to 2000 K, the new clusters keep a pod shape after self-assembly of C36 clusters; and above 2000 K, the structures of the final clusters change into a ball shape.
