Empirical relationship between track diameter and etching time for fission fragments incident on a glass SSNTD at various angles of incidence

Abstract

Geometrical shapes and diameter of nuclear tracks changes continuously during the process of etching for various incident angles. Besides, there is also a marked difference amongst their profiles, as evidenced by the SEM analysis, when the incoming particles fall on the detector at different angles of incidence. This work outlines this aspect of fission fragment tracks in a glass detector and has set out a few empirical relationship between the mean track diameter, d, and the etching time, t, within experimental limits. This study, therefore, sheds some light in the follow up the origins and chracteristics of heavy ions in some terrestrial and extra-terrestrial materials and also in studying the collimation accuracy of heavy ion bombardments. The implications of the results in discerning the measurements of incident angles of various types of ions are described in detail in the paper.
