摘要
Measurements of energy loss straggling for Li, C and O ions in varying thicknesses of mylar (C10H8O4) and polycarbonate (C16H14O3) absorber foils in the energy range similar to 3.0-6.0 MeV/u have been carried out, utilizing the Pelletron accelerator facility at Nuclear Science Centre, New Delhi, India. These measured values have been compared with the calculated values in order to establish the validity of various energy loss straggling formulations viz. Bohr, Lindhard and Scharff and Bethe-Livingston. From the energy loss straggling measurements in these two polymers having same atomic constituents and almost same effective Z, the validity of Bragg's rule has been checked. (c) 2005 Elsevier B.V.
