Penetration of Low-Energy Positrons through Thin Metallic Foils

Positron Implantation Profile in Kapton

“…Following the suggestions of Spanel et al [15] we argue that the shape of the implantation profile reflects not only the responsible for slowing down processes but also the shape of the energy spectrum of the implanted positrons. We have found that the implantation profile for monoenergetic positrons implanted randomly into the full solid angle in kapton exhibits almost perfect Gaussian shape.…”
