Proceedings of the specialists' meeting on "nuclear spectroscopy and condensed matter physics using short-lived nuclei 5"

Institute for Integrated Radiation and Nuclear Science, Kyoto University is a very useful neutron generator, providing us neutron-rich unstable nuclei by bombarding nuclei with those neutrons. The produced unstable nuclei exhibit aspects distinct from those of stable ones. Nuclear structure studies on a variety of excited states reflecting dynamic nuclear properties are one of fascinating research subjects of physics. On the other hand, some radioactive nuclei can be used as useful probes for understanding interesting properties of condensed matters through studies of hyperfine interactions of static nuclear electromagnetic moments with extranuclear fields. Concerning these two research fields and related areas, the 5th symposium under the title of "Nuclear Spectroscopy and Condensed Matter Physics Using Short-Lived Nuclei" was held at the Institute for two days on December 18 and 19 in 2018. We are pleased that many hot discussions were made. The talks were given on the followings: 1) Nuclear spectroscopic experiments, 2) TDPAC (time-differential perturbed angular correlation), 3) β-NMR (nuclear magnetic resonance), 4) Moessbauer spectroscopy, 5) Muons, 6) Ultracold neutrons, etc. All the 16 presented papers are indexed individually.
