Abstract
The recent implementation of gas-filled radiofrequency traps for efficient ion beam bunching extended the applicability of the Penning trap mass spectrometer ISOLTRAP/CERN to non-surface ionizable species. In a first series of successful runs the masses of 182–197Hg, 196,198Pb, 197Bi, 198Po and 203At have been determined with an accuracy of 1 · 10-7. In order to unambiguously determine the ground state mass the ground and isomeric states of 185,187,191,193,197Hg were separated applying a resolving power of up to 3.7 · 106. First experimental values for the isomeric excitation energy of 187,191Hg were obtained.
