Abstract :
The UV-Visible absorption spectra of virgin
and gamma irradiated (20–800 kGy) CR-39 polymer
have been deduced by using Shimadzu Double beam
Double Monochromator UV-Visible Spectrophotometer
(UV-2550). The existence of the peaks, their
shifting and broadening as a result of gamma irradiation
has been discussed. Finally the indirect and direct
band gap in virgin and gamma irradiated CR-39 has
been determined. The values of indirect band gap have
been found to be lower than the corresponding values
of direct band gap.
