Abstract

High-precision mass measurements of stable and beta-decaying nuclides ^52-57Cr, ⁵⁵Mn, ^56,59Fe, ⁵⁹Co, ^{75, 77-79}Ga, and the lanthanide nuclides ¹⁴⁰Ce, ¹⁴⁰Nd, ¹⁶⁰Yb, ¹⁶⁸Lu, ¹⁷⁸Yb have been performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE/CERN. The new data are entered into the Atomic Mass Evaluation and improve the accuracy of masses along the valley of stability, strengthening the so-called backbone. The mass of neutron-deficient ¹⁶⁸Lu in its isomeric state has been measured directly. The mass of neutron-rich ¹⁷⁸Yb indicates a change of nuclear structure approaching the double harmonic-oscillator shell closure for Z=70 and N=112.
