Signed by Abraham Pais. SIGNED IN JAPANESE BY ALL THREE AUTHORS. Abstract: "The mass, the life and the interaction with nucleons of 'I'-mesons discovered in photographic plates are qualitatively discussed. The probabilities of 'I'_x+lI'0 and 'I'-II'+r for various combinations of their couplings are calculated by Tomonaga-Schwinger formalism. The generalized selection tule lor the system composed of many mesons is presented, from which some patticular sets of the types 0. these mesons, fot example scalar and pseudoscalar, are admitted to explain the rather long life time of 'I'-meson, _10-11 sec. The life time for 'I'-.3x decay calculated by our method is obtained as long as 10-Il sec. consistent with experiments. This result suggests that the interaction of x-meson with nucleon is considerably weak. Some arguments for and against such presumption are discussed. The varieties of mesons, called varitrons, are classified as x- and p-types." Hayakawa: Hayakawa was a "well-known pioneer of astrophysics, having completed . . . a theory on the origin of cosmic rays and propsed . . . gamma ray astronomy. Later he was a leading proponent of X-ray astronomy and IR astronomy in Japan." :: Memoriam.

The Department of Physics, University of Tokyo. Signed by Abraham Pais. Abstract: "The experimental results concerning nuclear events in cosmic-ray underground, obtained by E. P. George and J. Evans by means of nuclear emulsions, were found to be in rather good agreement with the theoretical calculation, where the electromagnetic interaction of µ-meson with nucleon were treated in detail by Feynman-Dyson's procedure." KOSHIBA: (1926-) is a Japanese physicist. He jointly won the Nobel Prize in Physics in 2002 "for pioneering contributions to astrophysics, in particular for the detection of cosmic neutrinos". FUJIMOTO: physicist (born 1925-), studied at Tokyo University, taking his degree in 1947. He became a nuclear physicist, professor at Waseda University. Studied at Bristol University (1953-54), Assistant Professor at Kyoto University, facult of science, Professor at Tokyo University, Research Institute of Nuclear Physics. Member, Japan Society of Physics.
