Alpha – Particle Profiles

Abstract

To calculate the shape of the etch pits in the solid state nuclear track detector (SSNTD) with a depth dependent V , we used the generalized equations for the etch-pit profiles by using the variational principle, since these equations are applicable to the general case where neither the bulk nor the track etch rate is constant, these equations were used for analysis of etch pit shapes, by using cellulose nitrate as a detector, this analysis have been done for the first time. The calculated shape for the etch pit in cellulose nitrate, using the derived equations with depth dependent V , are in good agreement with the observed shapes.
