Ae. Barzakh et al., ISOTOPE SHIFT AND HYPERFINE-STRUCTURE MEASUREMENTS FOR YB-155 BY LASER ION-SOURCE TECHNIQUE, EUROPEAN PHYSICAL JOURNAL A-HADRONS AND NUCLEI, 1(1), 1998, pp. 3-5
The change in the mean square charge radius and electromagnetic moment
s of the neutron deficient Yb-155 isotope have been determined using r
esonance ionization spectroscopy in a laser ion source. The data point
to an absence of a marked deformation change for Yb isotopes with N=8
4-86.
