Transmission of positrons with aβ+ energy distribution through thin films
Abstract
The transmission through Al foils of isotropically implanted positrons from a22Naβ+ source has been measured. It is shown that the transmission is reasonably well-described using an exponential profile once backscattering is accounted for, except for thicknesses below approximately 7 mg/cm2. Below this thickness, the measured transmission is slightly less than that predicted by the exponential profile. Such a deviation has previously been …
