Description

Radioactive 191Os and 193Os nuclei have been aligned in an Os single crystal at temperatures down to 4 mK. From the temperature dependence of the γ-anisotropy the quadrupole frequencies vsub(Q) = e2qQ/h have been determined as vsub(Q)(191OsOs) = -278+-9 MHz and vsub(Q)(193OsOs) = -96+-15 MHz. With the known electric field gradient for OsOs of eq = (-4.54+-0.24) x 1017 V/cm2 the ground state spectroscopic quadrupole moments are deduced to be Q(191Os) = +2.53+-0.16 b and Q(193Os) = +0.87+-0.15 b.
