An experimental method for precise measurements of straggling in energy loss of 1H and 2H ions in composite materials: Application to polymer foils

Energy loss straggling data of 28Si, 27Al, 24Mg, 19F, 16O, and 12C heavy ions in thin polymeric Formvar foil over a range of energies 0.1–0.6MeV/u by time-of-flight spectrometry

“…Following our investigation in this field (Ammi et al, 2002), this work will provide a new set of straggling data which will be useful for comparison with different straggling formulations. A large amount of experimental straggling data is available for a great variety of incident ions and target materials of different natures (Sofield et al, 1978;Herault et al, 1988;Yang et al, 1991;Ouichaoui et al, 2000;Ammi et al, 2002Ammi et al, , 2004Ammi et al, , 2006Diwan et al, 2011;Mammeri et al, 2012).…”

In particular, more experimental data has been added in recent years principally for light ions in thin polymeric foils (Ammi et al, 2002(Ammi et al, , 2004(Ammi et al, , 2006Mammeri et al, 2012) by combining the Rutherford backscattering spectrometry and the transmission techniques.…”

The straggling data measured this way were usually found to be in qualitative agreement with the available theoretical straggling models (Bohr, 1948;Livingston and Bethe, 1937;Titeica, 1939;Lindhard and Scharff, 1953;Chu, 1976) combining with the Bragg additivity rule (Bragg and Kleeman, Contents 1905) for compound materials.…”
