Smooth trends in fermium charge radii and the impact of shell effects

NUCLEAR MOMENTS ^{245,246,248,249,250,254,255,257}Fm, ²⁵⁵No; measured laser frequencies; deduced the isotope shifts in atomic transitions, nuclear mean-square charge radii, a transition to a regime in which shell effects have a diminished effect on the size compared with lighter nuclei. Comparison with a range of nuclear models based on energy density functionals. The recoil separator SHIP (Separator for Heavy Ion reaction Products) at GSI Helmholtzzentrum fur Schwerionenforschung and the gas-filled RADRIS stopping cell.
