Mass measurements of Xe-114-124,Xe-130 with the ISOLTRAP penning trap spectrometer

The masses of the xenon isotopes with 114 less than or equal to A less than or equal to 123 were directly measured for the first time. The experiments were carried out at the ISOLTRAP triple trap spectrometer at the online ma ss separator ISOLDE/CERN. A mass resolving power of the Penning trap spectr ometer of m/Deltam approximate to 500 000 was chosen and an accuracy of del tam approximate to 12 keV for all investigated Xe isotopes was achieved. An atomic mass evaluation was performed and the results of this adjustment ax e compared with theoretical predictions. The new results for the xenon isot opes and their effects on neighboring nuclides are discussed within the two -neutron separation energy picture.
