“…Spurný et al (1987) have shown that proton tracks in CN-85 can be revealed by an electrochemical etching method. Faghih-Habibi and Afarideh (1994) have demonstrated that CN-85 can register proton and deuteron tracks in the energy range of 1-2 MeV (these energies do not represent the lower and upper energy limits for detection of protons in CN-85) and normal chemical etching can reveal tracks of these ions.…”
