论文摘要

提出了由20ne10+梁在15 meV/u碰撞的各种薄固体目标上产生的电荷状态分布的新实验测量。 MAGNEX磁光谱仪的使用实现了8+电荷状态的测量值，向下达到了几个10-5的分数。探索了主要目标下游的不同旋转后箔的使用，这表明低Z材料对于将电荷状态分布向完全剥离的条件转移特别有效。还研究并讨论了对箔厚度的依赖性。

New experimental measurements of charge state distributions produced by a 20Ne10+ beam at 15 MeV/u colliding on various thin solid targets are presented. The use of the MAGNEX magnetic spectrometer enabled measurements of the 8+ charge state down to fractions of a few 10-5. The use of different post-stripper foils located downstream of the main target is explored, showing that low Z materials are particularly effective to shift the charge state distributions towards fully stripped conditions. The dependence on the foil thickness is also studied and discussed.
