Preliminary Study of Natural Alpha Particle Track Through Solid State Nuclear Track Detector, CR-39.

Abstract

Measurements of alpha particle tracks parameters from 10B(n,𝛼)7Li nuclear reaction by thermal neutron emitted from 241Am-Be neutron source were reported by using solid state nuclear track detector CR-39 the said detectors were chemically etched in a 6.25 N aqueous solution of NaOH at 70°C for periods of 1 to 5 hours. The dependence of track diameters as a function of whole etching time, the divergence of the alpha’s track etch rate and the etch rate ratio as a function of different incident energies of alpha particle are presented and discussed.
