“…However, indications that these detectors can be used in principle at least, for charged particle energy analysis have come from studies related to tracks longitudinal profiles development. These properties include the track etch rate (V T ), the ratio of the bulk etch rate (V=V T /V B ) and the track saturation lengths (L S ) (Lounis et al, 2001;Nikezic and Yu, 2004;Balestra et al, 2007;Hermsdorf, 2011, Zaki et al, 2012. This is because these properties are directly related to the particle range (R) in the plastic material, which is direct measure of energy.…”
