Angular dependence of the PAC spectrum in a quenched single crystal of cadmium

To examine the orientation and magnitude of the electric field gradient (EFG) created by a vacancy at the111In probe site, PAC spectra were measured in a Cd single crystal as a function of the crystal orientation after a quenching and aging treatment at 120 K. The results are compared with calculated spectra based on a point charge model of the EFG created by a vacancy at the site of the probe atom.
