Columbia Resin-39 (CR-39) detectors used in Pd/D co-deposition experiments were examined using an optical microscope, scanned using an automated scanner, and underwent both sequential etching analysis as well as LET spectrum analysis. These analyses identified and quantified the energetic particles responsible for the tracks observed in the CR-39 detectors and made it possible to estimate the branching ratios of the primary and secondary reactions.

Abstract


Columbia Resin-39 (CR-39) detectors used in Pd/D co-deposition experiments were examined using an optical microscope, scanned using an automated scanner, and underwent both sequential etching analysis as well as LET spectrum analysis. These analyses identified and quantified the energetic particles responsible for the tracks observed in the CR-39 detectors and made it possible to estimate the branching ratios of the primary and secondary reactions.
