The annealing behavior of fission fragment tracks in CR-39 has been studied
at different temperatures for various time intervals. Experimental data, o
btained in isothermal and isochronal annealing experiments carried out on C
R-39 irradiated with fission fragments of Cf-252, has been analyzed on the
basis of different annealing models. It has been attempted to find out the
validity of these models, developed on the basis of annealing data in miner
als and other detectors, to the annealing data of fission fragment tracks i
n CR-39. (C) 2000 Elsevier Science B.V. All rights reserved.
