Outline of Final Research Achievements

Charge exchange cross section (σp) and collisional destruction cross section (σd) with several gas targets were obtained for linear-chain form cluster, C2 - C10, and cage form cluster, C60, in MeV energy using a charge exchange section in a tandem accelerator. The result suggests that linear-chain cluster ions tend to be oriented to a beam axis in the accelerator. We measured orientational distribution of C2 ions to a beam axis after colliding with target gases in the accelerator using a cluster ion orientation measurement system. As a result, orientational distributions depended on a target gas. These results suggest that a geometrical cross section of cluster ion might be important parameter as charge exchange and destruction interactions of cluster ions with gases.
