Abstract

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 to approximately 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.
