| Abstract: | The masses of the noble-gas Xe isotopes with
have been directly measured for the first time. The experiments were carried out with the ISOLTRAP triple trap spectrometer at the on-line mass separator ISOLDE/CERN. A mass resolving power of the Penning trap spectrometer of
of close to a million was chosen resulting in an accuracy of
keV for all investigated isotopes. Conflicts with existing, indirectly obtained, mass data by several standard deviations were found and are discussed. An atomic mass evaluation has been performed and the results are compared to information from laser spectroscopy experiments and to recent calculations employing an interacting boson model.PACS:
