本文提出了一种计算快速分子离子穿越薄箔时碎裂产生的原子离子电荷态的方法。考虑到每个原子离子的电荷状态中的相邻离子的相互影响以及每个离子离开箔时靠近出射表面的屏蔽中的不对称性。我们发现后一种效果特别重要。我们的计算比较非常好的实验数据可用于不同的分子离子和箔厚度。
We present a method to calculate the charge state of the atomic ions resulting from the fragmentation of swift molecular ions when traversing thin foils. The mutual influence of the neighbouring ions in the charge state of each atomic ion and the asymmetries in the screening close to the exit surface as each ion leaves the foil is taken into account. We have found the latter effect to be particularly important. Our calculations compare remarkably well with experimental data available for different molecular ions and foil thicknesses.
