In the current study, the bulk etch rate VBof solid state nuclear track detectors SSNTDs CR-39 have been examined at different concentrations of NaOH solution ranged from 4N to 8N and different temperatures of NaOH solution (50, 60, 70, 80°C) for various time intervals of etching (1-10 h); this is done by determination of mass variation via etching time. The results indicate that the bulk etch rate VBincreases with the increase of etchant solution concentration and the temperature of solution. This can be attributed to the increase the thickness of the removed layers h of the detector.

This study gives information about the effects of UV (here, the wavelength is 160 nm) exposure on the bulk etch rate ([Formula: see text], track etch rate ([Formula: see text], the detector sensitivity ([Formula: see text], critical angle ([Formula: see text] and etching efficiency ([Formula: see text] of Makrofol-E Solid State Nuclear Track Detector. The effect of UV on the activation energy of Makrofol-E was also studied. Nine pieces of Makrofol-E Solid State Nuclear Track Detector were separated into three equal sets as set A, set B and set C. Set A, named as reference set (Fission fragment FF), was irradiated to [Formula: see text]Cf source. Set B, called as post-exposed ([Formula: see text]), was first irradiated to [Formula: see text]Cf and then exposed to UV. The process was reversed for set C named as pre-exposed ([Formula: see text]) at the same conditions. From the results, it is concluded that radiation produces small but significant effect on activation energy [Formula: see text] of bulk etch rate for pre-exposed and post-exposed samples. Also, the activation energies [Formula: see text] of track etch rate for post-exposed and Fission fragment samples are within experimental uncertainty. The energy carried by UV radiation may be responsible for cross networking processes occurring during the exposure which results small change in activation energies for both [Formula: see text] and [Formula: see text]. The [Formula: see text] can be increased by hardening detector material of the pre-exposed detector.

Correlation Criterion

We have investigated Uranium ions interaction at energy 14.0 MeV /u incident on a Vanadium target using mica as nuclear track detector. The detector exposure was made from ions beam facility at UNILAC accelerator of GSI Darmstadt, Germany. The etched detector was scanned using an optical microscope. From the total binary tracks data events, elastic track events were separated using angular correlation criterion. The elastic scattering data have been separated from the binary events and used for the determination of quarter-point angle θ1/4 (grazing angle). Total and partial reaction cross-sections are measured using the statistic of inelastic two-pronged and higher multiplicity tracks. The experimental measured cross-sections are compared with the cross-sections calculated using sharp cut-off model. The theoretical prediction of reaction parameters of interacting heavy ions have also been determined, that are comparable with experimental measured values.
