Ratio of Static Electric-Quadrupole Moments ofK=3andK=0States inYb172

Abstract

The ratio of the electric-quadrupole interaction frequencies between the $3^{+}$ 1174-keV state and the 79-keV $2^{+}$ state has been measured using time-differential perturbed angular correlation techniques. The measured ratio $\frac{{\omega }_0\mathrm{}\left(1174\right)\mathrm{}}{{\omega }_0\mathrm{}\left(79\right)\mathrm{}}=0.53\mathrm{}\pm 0.06$ corresponds to a ratio of the static quadrupole moments of $\frac{Q\left(1171\right)\mathrm{}}{Q\left(79\right)\mathrm{}}=1.33\mathrm{}\pm 0.15$, which, combined with the value of $Q\left(79\right)\mathrm{}$ derived from Coulomb-excitation transition probabilities, yields a value of $Q\left(1174\right)=2.92\mathrm{}\pm 0.33$ b.
