Abstract content
Multi-prong tracks have been recorded in the polyethylene terepthalate (C10H8O4) solid-state nuclear track detector by exposing it to a 252Cf fission source. After etching with 6.25N NaOH solution at temperature 55±0.1 C, for four hours, two-prong to six-prong tracks along with single tracks were observed under the objective of an optical microscope. Cross section of fragmentation decreases with multiplicity of the event. Charges of the fragments lie in between 8
