Proceedings of the 2nd KUR symposium on hyperfine interactions

Hyperfine interactions between a nuclear spin and an electronic spin discovered from hyperfine splitting in atomic optical spectra have been utilized not only for the determination of nuclear parameters in nuclear physics but also for novel experimental techniques in many fields such as solid state physics, chemistry, biology, mineralogy and for diagnostic methods in medical science. Experimental techniques based on hyperfine interactions yield information about microscopic states of matter so that they are important in material science. Probes for material research using hyperfine interactions have been nuclei in the ground state and radioactive isotopes prepared with nuclear reactors or particle accelerators. But utilization of muons generated from accelerators is recently growing. Such wide spread application of hyperfine interaction techniques gives rise to some difficulty in collaboration among various research fields. In these circumstances, the present workshop was planned after four years since the last KUR symposium on the same subject. This report summarizes the contributions to the workshop in order to be available for the studies of hyperfine interactions. (J.P.N.)
