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 ^{185,187,191,193,197}Hg 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.
