Abstract

The electric-field-gradient tensor at the site of the impurity atoms 71,73As and 69Ge in orthorhombic gallium was measured by the time-differential perturbed angular distribution method. To analyze the spectra for the long-lived 73As isomer, an autocorrelation technique was developed. The tensor orientations found are quite different from those observed for Ga lattice atoms and Cd impurities.
