摘要：

Precise energy values for ten standard γ-ray reference lines produced in the radioactive decay of 170Tm and 169Yb have been measured relative to an optical standard. These measurements, which have an uncertainty of about 0.5 ppm for the more intense lines, provide precise γ-ray standards in the 63-307 keV range. Measurements on 169Yb lines constrained by the Ritz principle satisfy the combination principle within the measurement uncertainty. © 1979.
