Abstract

Polyvinyl alcohol films were irradiated to 90 MeV O6+and 150 MeV Si14+ions at fluence ranging from 1010to 1012ions/cm2. The observed changes in optical energy gap of this polymer have been investigated and results are tried to be explained in terms of energy transferred by the incident ions. It has been noticed that the value of optical energy gap decreases with increasing energy loss during the ion–polymer interaction process. [ABSTRACT FROM AUTHOR]
