Fig. 4: Signal sensitivity of LPT experiments.
From: Enhanced sensitivity for electron affinity measurements of rare elements
Signal sensitivity as a function of the photon energy above the threshold evaluated for this work (red circles), as well as for selected single-passage LPT measurements: Berzinsh et al.53 on Cl (gray squares) and Rothe et al.31 on I (blue open diamonds). The horizontal solid lines indicate the weighted averages for each experiment. The dashed line represents the signal sensitivity ideally required for one-atom-at-a-time LPT experiments, implying S/Nanion ≈ 1. Error bars represent 1σ uncertainty.
