✦ Synopsis

The Penning trap mass spectrometer ISOLTRAP, installed at the on-line isotope separator ISOLDE at CERN, has been used to measure atomic masses of 88,89,90m,91,92,93,94 Rb and 91,92,93,94,95 Sr. Using a resolving power of R ≈ 1 million a mass accuracy of typically 10 keV was achieved for all nuclides. Discrepancies with older data are analyzed and discussed, leading to corrections to those data. Together with the present ISOLTRAP data these corrected data have been used in a general mass adjustment.
