| Abstract: | The behavior of polymers under heavy ion bombardment is of great interest. In the present study, hydrogen released from polypropylene (PP) and polyethylene terephthalate (PET) was investigated as a function of charge state (11+, 14+, and 25+) for 130 MeV 107Ag ions. It was found that hydrogen released from the polymers varies as α q n , where n was found to be 2.98 and 1.94 for PP and PET, respectively, when compared with the value of ～3.0 reported in the literature for different polymers and ion combinations. Radii of the damaged zones or ion track formed were deduced from the slope of the hydrogen released versus ion fluence curves. This radius was also found to depend upon the charge state of the incident ion. It varies as β q m , where m is 1.25 and 0.741 for PP and PET, respectively. |
