摘要：

Fluorescence spectra from atoms of radioactive nuclides produced by heavy-ion fusion reactions have been measured on line with a gas-filled, liquid-nitrogen-cooled resonance cell. This device yields useful spectra from Yb nuclides produced at rates lower than 1000 s-1. Spectra have now been obtained for Yb isotopes more than 18 neutrons away from the line of beta stability. These data show a large isotope shift surprisingly near the N = 82 shell closure. The apparatus has also been used to measure isotope shifts of the refractory element Hf.
