Abstract

For experimental treatments of atomic clusters, a FT-ICR (Fourier Transform Ion Cyclotron Resonance) spectrometer with a direct injection supersonic cluster beam source was implemented. Newly designed ICR cell in 6 Tesla superconducting magnet was proved to give a high mass-resolution for positive and negative cluster ions. With this mass-spectrometer, pure carbon and metal-carbon binary clusters generated by the laser-vaporization supersonic-expansion cluster-beam source were studied. A special cluster beam source condition was found where only C 60 + was observed for pure carbon clusters. Furthermore, positive lanthanum-carbon, yttrium-carbon and scandium-carbon binary clusters showed only MC 2n + signal in the range of 36≤2n≤76 with strong magic numbers at MC 44 + , MC 50 + and MC 60 + . Characteristics of these small clusters were compared with results of molecular dynamics simulations.
