Phys. Rev. Lett. 102, 112501 (2009) [5 pages]Discovery of 229Rn and the Structure of the Heaviest Rn and Ra Isotopes from Penning-Trap Mass MeasurementsReceived 4 November 2008; published 19 March 2009 The masses of the neutron-rich radon isotopes 223–229Rn have been determined for the first time, using the ISOLTRAP setup at CERN ISOLDE. In addition, this experiment marks the first discovery of a new nuclide, 229Rn, by Penning-trap mass measurement. The new, high-accuracy data allow a fine examination of the mass surface, via the valence-nucleon interaction δVpn. The results reveal intriguing behavior, possibly reflecting either a N=134 subshell closure or an octupolar deformation in this region. © 2009 The American Physical Society URL:
