Abstract

A 41-cm double-focusing mass spectrometer has been used to measure atomic masses of ${}^{167}{Er}$ , ${}^{168}{Er}$ , ${}^{179}{Hf}$ , ${}^{180}{Hf}$ , ${}^{189}{Os}$ , and ${}^{190}{Os}$ . The measurements have yielded absolute atomic masses with errors less than 5 μu.

NUCLEAR STRUCTURE ${}^{167, 168}{Er}$ , ${}^{179, 180}{Hf}$ , ${}^{189, 190}{Os}$ measured atomic masses. Compared with earlier results.
