Abstract

Mass measurements with the ISOLTRAP mass spectrometer at CERN-ISOLDE improve mass uncertainties
of neutron-deficient tin isotopes towards doubly magic 100Sn. The mass uncertainty of 103Sn was reduced by a
factor of 4, and the new value for the mass excess of −67104(18) keV is compared with nuclear ab initio and
density functional theory calculations. Based on these results and local trends in the mass surface, the masses
of 101,103Sn, as determined through their QEC values, were found to be inconsistent with the new results. From our measurement for 103Sn, we extrapolate the mass excess of 101Sn to −60005(300) keV, which is significantly more bound than previously suggested. By correcting the mass values for 101,103Sn, we also adjust the values of 104Sb, 105,107Te, 108I, 109,111Xe, and 112Cs near the proton drip line which are connected through their α and protonQ values. The results show an overall smoothening of the mass surface, suggesting the absence of deformation energy above the N = 50 shell closure.
