The on-line measurements presented here were performed at the velocity filter SHIP at the GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt (Germany) in the frame of FAIR Phase-0. We thank the GSI ion source and accelerator operation groups for the preparation of a stable 48Ca and 40Ar beam, and the GSI target laboratory for providing high-quality targets. The isotopes used in this research were provided by the US Department of Energy Office of Science Isotope R&D and Production Program. The 253,254,255Es and 255,257Fm were supplied to Florida State University and the University of Mainz via the processing at the Radiochemical Engineering Development Center at Oak Ridge National Laboratory. Separation of the einsteinium and fermium at ORNL was supported in part by the US DOE Office of Science, Heavy Element Chemistry programme. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement number 861198-LISA-H2020-MSCA-ITN-2019 and under grant agreement number 654002 (ENSAR2).
