We report on the measurements of the total charge changing fragmentation cross sections in high-energy nucleus-nucleus collisions using Fe, Si and Pb incident ions. Several stacks of CR39 nuclear track detectors with different target combinations were exposed at normal incidence to high energy accelerator beams to integrated densities of about 2000 ions/cm^2. The nuclear track detector foils were chemically etched, and ion tracks were measured using an automatic image analyzer system. The cross section determination is based on the charge identification of beam ions and their fragments and on the reconstruction of their path through the stacks.

Electron-ion-ion coincidence experiments for photofragmentation of polyatomic molecules using pulsed electric fields: treatment of random coincidences
在通过软X射线的分子光致碎裂过程中,可以产生许多离子碎片,每个离子碎片具有不同的丰度和与发射的电子动能的相关性。为了研究这些碎裂过程,电子-离子和电子-离子-离子符合实验是非常强大的,其中使用静电分析仪分析电子的动能,同时使用脉冲电场分析离子的质量。然而,对于这样的测量,随机巧合的贡献是巨大的,并以非平凡的方式影响数据。不能应用简单直观的减法。在本文中,我们描述了这些电子-离子和电子-离子-离子符合实验,以及随机符合贡献的扣除方法。我们提供了一套全面的数据处理方程,包括计算误差条的方程。我们通过将其应用于游离CF $_3$ SF $_5$分子的片段化来证明该方法。
