The correlation between energy-loss and collected-charge for individual ions traversing 7.1 μm self-supporting Si p–i–n ΔE detectors has been studied using the Enge spectrometer at the Australian National University. In this work the simultaneous measurements of the ΔE signal and energy-loss were made for 49 MeV 28Si and 103 MeV 28Si and 147 MeV 74Ge incident ions obtained by 10° scattering of a primary beam from a thin gold target supported on a carbon foil. The results show that there exists a strong correlation (correlation coefficient r∼0.9) between the individual ions energy-loss and the collected-charge signal. Consequently the distributions of collected-charge and energy-loss are closely similar. The energy-loss distributions exhibit high energy-loss tails that may be attributed to asymmetry in the distribution of electronic energy-loss and/or to trajectory length spreading as a result of single and multiple scattering in nuclear collisions.
