描述This volume deals with the interaction between moments of excited or radioactive nuclei and electromagnetic fields. The experimental techniques developed for the observation of this hyperfine interaction are governed by the lifetime of the nuc­ lear states in question. The dynamics of the interaction are reflected by the time dependence of the spatial distribution of the radioactive decay radiation. Basically, the experiments yield information on the energy shifts and/or splittings of the nuc­ lear levels. These quantities are determined essentially by the product of the nuc­ lear moment and the electromagnetic field acting at the site of the nucleus. Due to the strong decrease in the fields with distance, the measurements probe these fields within a highly localized region centered around the radioactive nuclei. Detailed experimental methods with numerous ramifications were developed in the early sixties. In the period which followed, the main emphasis was on excitation of short-lived nuclear states by means of pulsed particle accelerators, implantation of radioactive nuclei, and production of polarized a-unstable nuclei by nuclear re­ actions with polarized neutrons or particles.

Introduction,tipole expansion: . where H(E0) denotes the electric monopole, H(M1) the magnetic dipole, H(E2) the electric quadrupole term, etc. They correspond to the moments of the nucleus not required by symmetry to vanish.

Hyperfine Interactions of Excited Nuclei in Atomic Systems, chapter. Because of the existence of this excellent review by GOLDRING, which places strong emphasis on the time integral methods, I have tended in this chapter to emphasize more the techniques and methods for dealing with longer-lived nuclear levels where one can apply time differential methods.

Electric Quadrupole Interaction in Noncubic Metals,is field. Its advantages, essential for QI studies in metals, are the ease with which temperature and pressure dependencies can be measured and the applicability to pure metals as well as to systems with extremely diluted impurity probe atoms. Thus, most experimental data have been obtained by this technique during the last few years.

Introduction,the constituents of the solid-state surroundings, or by totally external sources such as an applied magnetic field. This hyperfine interaction results in a shift and a splitting of the nuclear and atomic levels. The hyperfine interaction Hamiltonian H. can be expressed conveniently in terms of a mul

Hyperfine Interactions of Defects in Metals,ed themselves rather impetously, among them the subject of defects in metals. Information on defects have so far been extracted from macroscopic physical properties like electric resistivity or elastic modulus; in contrast to this the hyperfine methods permit a microscopic glance onto the defect beh

Electric Quadrupole Interaction in Noncubic Metals,harge distribution creates an electric field gradient (EFG). The quadrupole hyperfine interaction (QI) between the nuclear quadrupole moment Q and the EFG at the site of the nucleus results in an energy-splitting of the nuclear levels. The investigation of this QI in noncubic metals and alloys can b
