摘要
研究了每核子能量为 2 6 0— 4 5 0keV的H+ 2 ,H+ 3 ,H+ 4 H+ 5和H+ 7团簇离子在金膜中的能损 .发现团簇离子中平均每个质子的能损大于相同速度的单质子能损 ,即能损比大于 1,且随团簇离子的大小和速度的增加而增加 .
The energy losses of cluster ions H + 2, H + 3, H + 4, H + 5 and H + 7 with energy of 260-450 keV/p in solid films have been measured. It has been found that the energy loss per proton in clusters is larger than that of single proton with the same velocity as clusters, that is, the energy ratio is larger than 1. Energy ratio increases with increasing the cluster size and velocity.
