Abstract
The effect of induced crystallinity by preirradiation annealing on range energy relationships have been investigated for a number of energetic ions and Cf-252 fission fragments in polymer dielectric nuclear track detectors DNTDs. The stopping power of the defferent polymeric detectors (cellulose based derivatives), have been examined in the solid (amorphous and crystalline) phases. X-ray diffraction of annealed CA80-15 (made by Kodak Pathe' France) and other polymers show a general decrease in (dE/dX) and hence variations of electron density distribution, leading to increased penetration ranges for charged particles in DNTDs.
