Focuses on a study of how the study of one subject can lead to another subject of exotic atoms that involves both high-energy physics and nuclear physics. Characteristics of exotic atoms; Steps in making exotic atoms with negative mesons; Kinds of exotic atoms and their behavior; Significant aspect of kaonic reaction.

Provides information on the high-energy scattering of the fundamental particles of matter. Overview of high-energy collision between a fast-moving negative pion, or pi meson, and a stationary proton; Evolution of the creation and study of the subnuclear constituents of matter; Discussion on the assumption that energy momentum and electric charge are conserve in scattering events; Discussion on the interactions of fundamental particle.

The article recounts the events surrounding the discovery and production of the omega-minus particle, which may support the organization of particles inside the atomic nucleus as proposed by Murray Gell-Man of the California Institute of Technology and independently by Yuval Ne'eman of Tel Aviv University in Israel. Omega-minus particle would be produced from K-minus mesons shot in the bubble chamber to interact with a proton in the liquid hydrogen.

The article presents a study about artificial atom in which an electron is replaced with a meson. Mesons are middleweight particles which are about the weight between an electron and proton, and are be connected with the forces inside the atomic nucleus. Scientist Niels Bohr points out that if energy is supplied to the atom, the electron may leave its orbit and jump momentarily to an orbit farther from the nucleus.

Reports on the identification of two new subatomic particles from several photographs of nuclear events at the Brookhaven National Laboratory in New York in 1969. Prediction on the existence of the particles by the SU(3) theory of elementary particles; Application of the theory on interacting particles baryons and mesons; Members of the xi class particles that were identified before the subatomic particles.

The article describes an experiment carried out at the Brookhaven National Laboratory by Val L. Fitch, James H. Christenson, James W. Cronin and Rene Turlay of Princeton University regarding the so-called fifth force in nature. They found that two times out of 1,000 the K-two-zero meson decays into two pi mesons instead of three pi mesons.

Since the end of the war the focus of interest in physical science has not been the atomic pile or the atom bomb but a family of unfamiliar sub-atomic particles known as mesotrons or mesons. Mesons are among the debris left when atoms in the earth's atmosphere are struck by cosmic rays, the mysterious super-powerful radiation that rains ceaselessly on the earth from outer space. The great interest in mesons arises from the fact that they are taking physicists into a new world. The release of atomic energy in the atomic pile and bomb conveys the impression that few secrets remain to the atom.
