Abstract
The quadrupole frequencyv Q =e 2 qQ/h of103Ru (Z=44,N=59) in a ruthenium single crystal has been measured using the technique of low temperature quadrupole orientation to bev Q (103RuRu)=−14.7(5) MHz. Temperatures below 2 mK were reached in this experiment using a PrNi5 demagnetization stage attached to a3He−4He dilution refrigerator. Using the measured magnitude of the RuRu electric field gradient (EFG) at low temperatures |eq(RuRu)|=1.02(3)×1017 V.cm−2 [1] and adopting the sign ofeq(RuRu) to be negative from systematics, this result yields a value for the ground-state electric quadrupole moment of103Ru ofQ(103Ru)=+0.59(2) b. This moment may be interpreted using the weak coupling model of de-Shalit [2]. A Korringa constant for103RuRu ofC K=39(6) Ks was measured in this experiment. Taking advantage of a small iridium contamination of the ruthenium single crystal, the quadrupole moment of the192Ir ground state was determined to beQ(192Ir)=+2.12(25) b. The sign of the IrRu electric field gradient was found to be negative as a result of this work.
