LATENT NUCLEAR TRACKS OR NANOPOROUS RODS: DEFECT STRUCTURE AND DAMAGE REPAIR DURING ANNEALING *M.

M. A. Rana

Abstract


Experimental results on the subject of defect structure of latent nuclear tracks and their damage repair during annealing
in a track detector CR-39 are presented. These results suggest that latent nuclear tracks can be considered as
nanoporous rods with nanometre scale pores along the central axis of the cylindrical track. An overview of a model
about repair of radiation damage in solids is given. Model calculations are compared with experimental results regarding
repair of nuclear track damage in CR-39. A convincing agreement is found between experimental results and model
calculations. Results and discussion presented here are useful for better interpretation of results from nuclear geology
and cosmic-ray physics experiments.
