Track structure in polyethylene terephthalate irradiated by heavy ions: LET dependence of track diameter. Apel, P.; Spohr, R.; Trautmann, C.; Vutsadakis, V.. Radiat. Meas. (1999), 31(1-6), 51-56

The structure of latent tracks in polyethylene terephthalate is studied using chemical etching combined with a conductometric technique. Geometrical parameters of the latent tracks for the range of the electronic energy loss (dE/ dx) between 3 to 24 keV/nm are estimated. The dependence of the track core and track halo size on the energy loss is analyzed (10 refs.)
