Abstract

A high-accuracy mass measurement of Li7 was performed with the SMILETRAP Penning-trap mass spectrometer via a cyclotron frequency comparison of Li3+7 and H2+. A new atomic-mass value of Li7 has been determined to be 7.0160034256(45)u with a relative uncertainty of 0.63 ppb. It has uncovered a discrepancy as large as 14σ (1.1μu) deviation relative to the literature value given in the Atomic-Mass Evaluation AME 2003. The importance of the improved and revised Li7 mass value, for calibration purposes in nuclear-charge radii and atomic-mass measurements of the neutron halos Li9 and Li11, is discussed.
