Exotic atoms and Nuclei



Exotic atoms and Nuclei

Particles like muons, pions, and kaons have finite life times, so they do not exist in natural nuclei or matters. Implanting these particles into nuclei/matters, exotic phenomena in varieties of objects can be studied from a new point of view. Kaon is a second lightest meson which has strange-quark as a constituent quark. It is expected that if one embed a kaon into nuclei, the sizes of the nuclei become smaller and forms a high density object beyond the normal nuclear density. Study of this object could lead better understanding of the origin of the mass of the matter, and may reveal the quark degree of freedom beyond the quark-confinement. Those properties can be studied by precise heavy pionic atom research in different angle. The other example is the weak interaction in nuclear matter. It can only be studied by the weak decay of hypernuclei, which have Lambda particle in the nuclei, Muon provides even wider variety of study from nuclear reaction to magnetism in matter.
