Abstract : A technique for the delineation of sub-surface charged particle tracks by a successive chemical removal of surface material is presented. A method of measuring the approximate range of heavily ionizing charged particles in polymers is given. The techniques are applied to the observation and measurement of low-energy He4 ion tracks in cellulose nitrate. (Author)
