Paper Abstract

New aspects of size- and state-specific properties of carbon cluster are described on the basis of experimental evidences obtained by recently developed clusterbeam apparatus. The present paper consists of mainly two topics. One of which is spin states for small carbon neutral clusters. Focusing effects induced by a hexapole magnetic field were examined for the carbon clusters from C1 to C6. The second is the study of cluster-solid surface interactions. Electron emission processes induced by collision of negative cluster ions with M0S2 single crystal were investigated in detail, paying special attention on the electron emission efficiency as functions of both size and incident kinetic energy. A new collision induced phenomenon has been found, which may be closely related with an electron detachment of negative ions induced by a surface potential of the solid target.
