Surface and Near-Surface Positron Annihilation Spectroscopy at Very Low Positron Energy
Lucian Mathes, Maximilian Suhr, Vassily V. Burwitz +3
We present a monoenergetic positron beam specifically tailored to the needs of (near-) surface positron annihilation spectroscopy. The Setup for LOw-energy Positron Experiments (SL…
