The atomic masses of the short-lived nuclides ¹⁷Ne and ¹⁹Ne have been measured with the triple-trap mass spectrometer ISOLTRAP at ISOLDE/CERN. The obtained mass excess for both nuclides deviates significantly from the literature value, in the case of ¹⁷Ne by about 40 keV. The mass value of ¹⁷Ne can be applied for a test of the isobaric multiplet mass equation with respect to an isospin T=3/2 quartet. In addition, both masses can contribute to the data analysis of collinear laser-spectroscopy experiments where mean-square nuclear-charge radii are determined.
