MEASUREMENTS OF RANGE AND ENERGY-LOSS OF PB-208 IN MAKROFOL-G

Ranges and energy loss of 17.1 MeV u(-1 208)Pb ions in Makrofol-G poly mer have been determined using a nuclear track technique. Calibrated p olyallyldiglycol carbonate (PADC) detectors were used to determine the degraded energy of (208)pb ions after they had passed through the var ious stacks of Makrofol-G. The energy-loss rates as a function of the depth of penetration and ion been determined. The mean ranges of Pb-20 8 in Makrofol-G have also been measured at various energies up to 17.1 MeV u(-1). The experimental results are discussed and compared with t he theoretical values obtained from four different computer codes.
