Statistical Analysis of Stopping Power of Polymers for Heavy Ions
This is a continuation of our earlier work (Radiation Effects & Defects in Solids, 163, No. 7, 2008, 605 - 623) for the up-to-date comparative study of various stopping power tables and codes for heavy ions (3 ≤ Z1 ≤ 29 ) in polymers using the statistical analyses in the energy range ~ 0.19-3.14 MeV/n. The SRIM (Stopping and Range of Ions in Matter) and CasP (Convolution approximation for swift Particles) formulations are now updated and their new versions (SRIM2008.04 and CasP4.0) are available in the literature. Six different polymers mostly used as particle track detectors viz: Mylar (Polyethylene Terephthalate), PEN (Polyethylene Napthalate), Polycarbonate, CR-39 (Polyallyl Diglycol Carbonate), Kapton (Polypyromellitimide) and LR-115 (Cellulose Nitrate) have been chosen for this investigation. The merits and demerits of these adopted formulations are highlighted in the present paper.
