The quadrupole moments of Zn and Cd isotopes—an update

The nuclear quadrupole moments of ¹¹¹*Cd (245 keV state) and ⁶⁷Zn were determined from the quadrupole coupling constants and lattice parameters of the metals at low temperature. The required electric field gradients were obtained with density functional calculations employing the WIEN2k code. The resultant numbers, 0.765(15) and 0.151(4) b, are in line with the previously used values but considerably more precise. Calculations for various other solids confirm the results, with less accuracy, however.
