| The radioactive decay of 172Lu--->172Yb appears to be suitable for time-differential perturbed angular correlation measurements of quadrupole interaction. The technique was applied to study various phenomena in three compounds: Yb3S4, YbPO4, Yb2Co3Ga9. We were able to distinguish between Yb2+ and Yb3+ ions occupying different positions in the crystal lattice of Yb3S4. Crystal electric field parameters reproduced the temperature dependence of the quadrupole interaction of Yb in YbPO4. Finally, the influence of hybridization on the 4f quadrupole moment in Yb2Co3Ga9 is evidenced. |
