Range and energy-loss rate of 118 MeV Si in some polymers using PADC as detector

Heavy ion range and energy-loss data provide useful information for designing several nuclear physics experiments where the polymers employed find their use as absorber, in chamber windows and target backings. In the present work, the range and energy-loss rate of 118 MeV ²⁸Si in LR-115 (cellulose nitrate) and polypropylene (PP) have been calculated by track technique where polyallyldiglycol carbonate was used as a backing detector. The mean range of ²⁸Si in LR-115 has been calculated to be 59.4±2 μm and that in PP is calculated to be 74.9±2 μm. The experimentally evaluated range values are in agreement with the theoretical range values derived from some computer codes. The Bragg peak has also been obtained at 1.1 MeV/nucleon for ²⁸Si in both LR-115 and PP.
