N2 - Mass measurements with the ISOLTRAP mass spectrometer at CERN-ISOLDE improve mass uncertainties of neutron-deficient tin isotopes towards doubly magic Sn100. The mass uncertainty of Sn103 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 Sn101,103, as determined through their QEC values, were found to be inconsistent with the new results. From our measurement for Sn103, we extrapolate the mass excess of Sn101 to -60005(300)keV, which is significantly more bound than previously suggested. By correcting the mass values for Sn101,103, we also adjust the values of Sb104, Te105,107, I108, Xe109,111, and Cs112 near the proton drip line which are connected through their α and proton Q values. The results show an overall smoothening of the mass surface, suggesting the absence of deformation energy above the N=50 shell closure.
