Semi empirical equation for the calculation of the track diameter of alpha particles in CR-39 as a function of etching temperature

الملخص EN

In this paper a new semi empirical equation describing the track diameters of α particles in CR-39 is presented.

The equation involves three free fitting parameters.

It is shown that this equation can reproduce tracks diameter formed on the CR-39 by alpha particles at 3.1MeV, different etching times and temperature (70, 75, 80, 85) oC.

Parameters values obtained from the experimental data were used to predict etched track diameters at different temperatures (T = 70-85) oC and etching times (t = 0-6) h.

The suggested empirical equation is self consistent as far as reproducing all features of track diameter development as a function of etching time and temperature.
