摘要
The hybrid HF/DFT functionals in conjunction with small-core pseudopotential have been employed to investigate the geometric and electronic structures of small ThCn (n = 1-7) clusters. The fan-type isomers were found to be more stable than the linear ones. Analyses on the incremental binding energies indicate that the clusters with even C atoms possess the higher stability than odd-numbered ones. The interaction natures of Th-C chemical bonds were revealed by the methods of bond overlap density of states (OPDOS), adaptive natural density partitioning (AdNDP) and electron localization function (ELF).
