Low Energy Positron Interactions With Biological Molecules
<p>Calculations of the positron density distribution which can be used for positrons bound to midsize and larger molecules have been tested for smaller molecules and subsequently applied to investigate the most likely e+e- annihilation sites for positrons interacting with biological molecules …

Some effects on polymers of low-energy implanted positrons
The positron annihilation spectroscopy is a well established non-destructive tool to characterize materials and defects. Low-energy positron beams are suitable for thin-layer materials because a defined penetration depth of positrons can be obtained. This thesis is focused on two issues: 1. The …
