Hyperfine interactions in cubic metals using perturbed angular correlation techniques

This thesis consists of two parts. In the first an investigation is described of magnetic hyperfine fields of the s-type impurity atoms Zr, Cs, Ba and La in Fe and Ni. These eLements have a very low solubility in Fe and Ni, and, thereforer can not be introduced in the host metals by normal methods such as altoying or diffusion. Instead, they were implanted as radio-active ions with the aid of an isotope separator or by the recoil transferred in a nuclear reaction. ... Zie: Summary
