“…PI ( ρ = 1.42 g · cm −3 ) is a thermoplastic polymer; the chemical structure of PI consisting from imide and aromatic rings causes the improved heat resistance to and stability towards ionizing radiations . The declared thickness values of the PI foil were verified by repeatedly weighing a foil segment on a microbalance; the obtained value was 7.82 ± 0.3 µm. The foil thickness used in experiments was chosen according the ion projected range (to avoid any problems caused by ion implantation) and modification of the foils by the projectile ions and to follow preferably the electronic stopping in our experiments.…”

Polyimide (PI, (C22H10O5N2)n) foil, 8 µm thick, was irradiated with 9.6‐MeV C4+ and O4+ ions at fluences of 1010–1013 cm−2. Compositional and structural changes related to the ion species, ion irradiation fluence and the type of polymer were studied and discussed in connection with energy‐loss measurement. The knowledge of these changes of polymers after the irradiation is very important for the estimation of the influence of these effects on the experimentally determined ion‐energy losses. Rutherford back‐scattering (RBS) and elastic recoil detection analysis (ERDA) were used for the elemental composition study, atomic force microscopy (AFM) for the detection of the changes in surface roughness and UV–Visible spectral study (UV–Vis) for variation in the absorbance and the optical band gap. The chemical and structural changes, new radical appearance, and polymeric chain crosslinking especially at ion fluencies above 1013 cm−2 were observed and discussed in the frame of energy stopping experimental determination.

“…For incident hydrogen and helium ions on organic materials, corrections to Bragg's rule do apply [19], and they may be dealt with by the core-and-bond approach [9,20,21]. The same is true for 7 Li, 12 C, and 16 O ions in polymer foils [22].…”

Resonant nuclear reactions are a powerful tool for the determination of the amount and profile of hydrogen in thin layers of material. Usually, this tool requires the use of a standard of well-known composition. The present work, by contrast, deals with standard-less hydrogen depth profiling. This approach requires precise nuclear data, e.g. on the widely used 1 H( 15 N,αγ) 12 C reaction, resonant at 6.4 MeV 15 N beam energy.Here, the strongly anisotropic angular distribution of the emitted γ-rays from this resonance has been remeasured, resolving a previous discrepancy. Coefficients of (0.38±0.04) and (0.80±0.04) have been deduced for the second and fourth order Legendre polynomials, respectively. In addition, the resonance strength has been re-evaluated to (25.0±1.5) eV, 10% higher than previously reported. A simple working formula for the hydrogen concentration is given for cases with known γ-ray detection efficiency. Finally, the absolute approach is illustrated using two examples.

“…This information is important to understand the fundamental interactions and serve as an input to those experiments, where energetic ions are used. Numerous experimental and theoretical groups are involved to study the energy loss, in different target-ions' energy combinations, through different experimental techniques and by adopting different theoretical treatments (Ammi et al, 2011;Cantero et al, 2012;Diwan et al, 2003;Guesmia et al, 2014;Hubert, Bimbot, & Gauvin, 1990;Miksova, Mackova, Malinsky, Hnatowicz, & Slepicka, 2014;Moussa, Damache, & Ouichaoui, 2015;Northcliffe & Schilling, 1970;Paul & Schinner, 2001Pratibha, Sharma, Diwan, Kumar, Khan, & Avasthi, 2008;Randhawa & Virk, 1996;Rauhala, Raisanen, Fulop, Kiss, & Hunyadi, 1992;Sharma, Kumar, Yadav, & Sharma, 1995;Wambersie, 2005;Weaver & Westphal, 2002;Zhang & Weber, 2003;Ziegler, 1999;Ziegler, Biersack, & Littmark, 1985). As far as energy loss straggling is concerned, little attention has been paid and therefore limited studies are available, which are fragmentary in nature (Behar, Fadanelli, Abril, Garcia-Molina, & Nagamine, 2011;Besenbacher, Andersen, & Bonderup, 1980;Comfort, Decker, Lynk, Scully, & Quinton, 1966;Diwan, Neetu, & Kumar, 2012;Guesmia et al, 2015;Hsu, Liang, Yu, & Chen, 2005;Ibrahim & Al-Bedri, 2012;Kumar, Diwan, & Kumar, 2015;Miksova et al, 2014;Neetu, Sharma, Gulati, Diwan & Kumar, 2010;Ouichaoui et al, 2000).…”

Energy loss and straggling in Ag and Sn metallic foils for a-particles, using 241 Am source, are measured. The measured energy loss values are compared with the predicted values based on Benton and Henke, Grande and Schiwietz (CasP), Ziegler et al. (SRIM) formulations and ICRU-49 report (ASTAR). Also, measured straggling values of a-particles are compared with the computed values adopting practically used four collisional (Bohr, Lindhard and Scharff, BetheeLivingston, Titeica) formulations and one collisional plus charge exchange (Yang et al.) straggling formulation. The aim of the comparison is to identify the best energy loss and straggling formulation.
