摘要：

First results on fragmentation of fast ionic hydrogen clusters (n = 5-31, odd; 60 keV/amu) by single collision with a helium atom have been obtained with the new beams delivered by the variable energy post-accelerator of RFQ type at Institut de Physique Nucleaire de Lyon. The fragmentation apparatus and preliminary results are presented. The inclusive mass distributions of the charged fragments measured are strongly different from those resulting from lower energy collision. An important production of intermediate mass fragments is observed.
