Nuclear orientation of111mCd in Zn and Be and the quadrupole moment of the 245keV state

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

The 48.7 m111mCd activity was implanted in Zn and Be single crystals which were soldered to the cold finger of a dilution refrigerator and kept below 0.2 K during implantation. Subsequent nuclear orientation experiments allowed the determination of the quadrupole interaction frequencyv Q of the 11/2− isomeric state of111Cd in Zn and Be as −139 (15) MHz and +43(16) MHz respectively. With these results we derive the quadrupole moment of the 5/2+ 245 keV level of111Cd including sign asQ = +0.83(13) b and the sign of the electric field gradient for Cd in Be. The half-life of111mCd was redetermined as 48.67 (6) m.
