    “…A key result in the study of radioactive negative ions is presented with the determination of the electron affinity of astatine by means of collinear laser photodetachment spectroscopy. This experiment was performed utilising the Gothenburg ANion Detector for Affinity measurements by Laser PHotodetachment (GANDALPH), which underwent a detector upgrade to allow for operation in the UV spectrum using a novel, fully transparent graphene target. …”

    “…The p-type (111) is slightly more efficient than the p-type (100) and has a positronium lifetime of 142$\pm$1 ns, while the p-type (100) has a lifetime of 111$\pm$1 ns. Finally, laser excitation of positronium to the $n$=3 state with a UV laser pulse is demonstrated here for the first time, using lifetime spectroscopy.…”
