Throughout this work we present and analyse the inter-comparison result that we carried out between the energy loss straggling of ⁶³Cu, ²⁸Si, ²⁷Al, ²⁴Mg, ¹⁹F and¹⁶O partially stripped heavy ions crossing thin polymeric foils such as: Mylar, Polypropylene, Plexiglas and PVC, over a continuous range of energies 0.045–0.62 MeV/n, obtained experimentally and those calculated by the different theoretical formulations defining the energy loss straggling namely; straggling of Bohr, Bethe-Livingston, Lindhard-Scharff and the empirical formula developed by Yang et al. The experimental straggling data obtained in the framework with a precision of ±20% and nonexistent in the literature so far, have been generated by using Heavy Ion Elastic Recoil Detection Analysis (HIERDA) technique coupled with Time of Flight (ToF) spectrometer. In view of significant deviations obtained between experimental straggling data and those calculated theoretically, we can say that Bohr’s classical theory and other theories derived from Bohr’s classical theory (Lindhard-Scharff, Bethe-Livingston or Yang) are insufficient to describe correctly our obtained experimental straggling data over the investigated energy range.

在整个工作中，我们介绍并分析了在⁶³ Cu，²⁸ Si，²⁷ Al，²⁴ Mg，¹⁹ F和¹⁶的能量损失散失之间进行的比较结果在实验获得的能量连续范围为0.045-0.62 MeV / n的情况下，O的部分剥离的重离子穿过薄的聚合物箔，例如：聚酯薄膜，聚丙烯，有机玻璃和PVC，并且通过定义能量散失的不同理论公式计算得出。Bohr，Bethe-Livingston，Lindhard-Scharff的遗忘以及Yang等人开发的经验公式。通过使用重离子弹性反冲检测分析（HIERDA）技术与飞行时间（ToF）光谱仪结合，在框架中获得的实验性散乱数据的精度为±20％，并且迄今为止在文献中尚不存在。鉴于实验性散布数据与理论计算值之间存在明显差异，
