12C5+ radiation effects in SR-86 track recording polymer

摘要

The samples of SR-86 polymer were irradiatedwith 12C5+ ions of energy 5.0 MeV/u using fluences of 1011-1014ions/cm2 at NSC Pelletron in a high vacuum scattering chamber.The optical studies show an increase in absorption of UV or IR inthe shorter wavelength region (250-500nm). The study alsoreveals that the increase in radiation dose extends the opticalabsorption region to longer wavelengths. It is observed that thebulk etch rate of this polymer is enhanced after heavy ion irradiation.
