Annealing study of heavy ion tracks in Makrofol-n using electrochemical etching technique

252Cf fission fragment tracks in Makrofol-N were annealed and subjected to electrochemical etching keeping electrical and etching parameters constant for all observations. From diameter reduction rate, activation energy of annealing (Esub(a)) is determined. Results obtained are compared with those of chemical etching and it is found that the values of Esub(a) obtained independently by these two different techniques are in close agreement.
