Abstract

The electric field gradient (efg) present in noncubic solids causes an energy–splitting of the nuclear levels via the quadrupole hyperfine interaction. During the last few years the perturbed angular correlation method has proved a unique experimental tool for investigating this interaction especially in metals. The basic principles of the method are discussed. Recent experimental results are given for pure metals and highly diluted systems as well as for alloys and intermetallics. The last section deals with theoretical aspects of the temperature dependence of the efg in pure metals.
