Hideki Yukawa was born in Tokyo, Japan, on 23rd January, 1907, the third son of Takuji Ogawa, who later became Professor of Geology at Kyoto University . The future Laureate was brought up in Kyoto and graduated from the local university in 1929. Since that time he has been engaged on investigations in theoretical physics, particularly in the theory of elementary particles. Between 1932 and 1939 he was a lecturer at the Kyoto University and lecturer and Assistant Professor at the Osaka University . Yukawa gained the D.Sc. degree in 1938 and from the following year he has been, and still is, Professor of Theoretical Physics at Kyoto University. While at Osaka University, in 1935, he published a paper entitled "On the Interaction of Elementary Particles. I." ( Proc. Phys.-Math. Soc. Japan, 17, p. 48 ), in which he proposed a new field theory of nuclear forces and predicted the existence of the meson. Encouraged by the discovery by American physicists of one type of meson in cosmic rays, in 1937, he devoted himself to the development of the meson theory, on the basis of his original idea. Since 1947 he has been working mainly on the general theory of elementary particles in connection with the concept of the "non-local" field. Yukawa was invited as Visiting Professor to the Institute for Advanced Study at Princeton, U.S.A., in 1948, and since July, 1949 he has been Visiting Professor at

He invented a theory in which the force between protons and neutrons was mediated by a massive virtual particle of about 200 electron masses. In 1935, Carl Anderson discovered a particle in cosmic rays which he thought was Yukawa's particle. This particle was called a muon (or mu meson ). However, it did not strongly interact with nuclei so could not be Yukawa's particle. In 1947, however, Powell discovered the pion which satisfied all of Yukawa's postulates. Yukawa also predicted K-capture in which an electron in the lowest hydrogen energy level could be absorbed by the nucleus He received the 1949 Nobel Prize in physics for his prediction of the pion Additional biographies: Bonn References Yukawa, H.

Yukawa, Hideki Japanese physicist. In 1935 he discovered the strong nuclear force that binds protons and neutrons together in the atomic nucleus, and predicted the existence of the subatomic particle called the meson. Nobel prize 1949. Yukawa was born and educated in Kyoto and spent his career at Kyoto University, becoming professor 1939 and director of the university's newly created Research Institute for Fundamental Physics from 1953. Yukawa's theory of nuclear forces postulated the existence of a nuclear 'exchange force' that counteracted the mutual repulsion of the protons and therefore held the nucleus together. He predicted that this exchange force would involve the transfer of a particle (the existence of which was then unknown), and calculated the range of the force and the mass of the hypothetical particle, which would be radioactive, with an extremely short half-life. The muon, or meson, discovered 1936, fitted part of the description, and the pion, or meson, discovered 1947, fitted all of it. In 1936 Yukawa predicted that a nucleus could absorb one of the innermost orbiting electrons and that this would be equivalent to emitting a positron. These innermost electrons belong to the K electron shell, and this process of electron absorption by the nucleus is known as K capture.

In this 1934 draft manuscript, Japanese physicist Hideki Yukawa predicted the existence of a particle—a meson—with a mass about 200 times that of the electron. At first the muon, discovered in 1937, looked like a good candidate for the meson, but soon it became clear that the muon's properties did not match those predicted by Yukawa. Then, in 1947, Cecil Powell discovered the pi meson, or pion, which did have the predicted meson properties. We know now that the muon is an elementary particle, cousin to the electron, and that mesons, including the pion, are combinations of a quark and an antiquark.

Thayer Watkins Hideki Yukawa and the Pi Mesons Too often when Yukawa work is described only the predictions are noted so that it seems to the student that Yukawa just made a successful guess. This page's purpose is to present some of Yukawa's analysis that lay behind the successful prediction. When Hideki Yukawa wrote his article physicist were searching for the functional form of the strong force between nucleons (protons and neutrons). It was widely presumed, on the basis of the Coulomb force, that the strong force would be a power of the distance between the nucleons; i.e., 1/r n where r is the distance. Some proposed that the exponent n might be as large as 7 to account for the apparent short range of the nuclear force. Yukawa proposed the quite different form of: To see this, consider the case of radiation from a point source. Radiation creates pressure propagated by photons. The intensity of the radiation is inversely proportional to the square of the distance from the source; i.e., A/r . The number of photons (and consequentially the energy) on a wave front of radius r is the intensity A/r or A. The wave front would have the same energy (and energy) when it expands to a radius of r

The positive and negative pions have longer lifetimes of about 2.6 x 10 s. The negative pion decays into a muon and a muon antineutrino as illustrated below. This decay is puzzling upon first examination because the decay into an electron plus an electron antineutrino yields much more energy. Usually the pathway with the greatest energy yield is the preferred pathway. This suggests that some symmetry is acting to inhibit the electron decay pathway. The symmetry which suppresses the electron pathway is that of angular momentum, as described by Griffiths. Since the negative pion has spin zero, the electron and antineutrino must be emitted with opposite spins to preserve net zero spin. But the antineutrino is always

Today the concept of the nucleus of an atom as a cluster of protons and neutrons orbited by electrons is sufficiently familiar that is easy to forget that in at least one sense something one might not expect is going on. Within the tremendously dense nucleus, charged proton is pressed against charged protonin other words, positive charge hard against another positive. Extraordinarily powerful forces must be holding them against each other. In fact, this is called the Strong Forceit is the strongest of the 4 fundamental forces of nature which we understand to exist. (The other 3 are the Weak Force, Electromagnetic Force and Gravity.) By the early 1930s, Japanese physicist Hideki Yukawa concerned himself with the Strong Force, that force that holds together the nucleus. Not until 1947, with a marvelous new film from the Ilford Company exposed at a high altitude, was the meson's existence actually captured. The name "yukon" seems to have been seriously considered, but was thought to have been spoken for by the Canadian territory of the same name (though Yukons at many scales might have made a nice pattern for Powers of Ten Interactive). Yukawa won the Nobel Prize in 1949. His mesons are now known as pions (or pi-mesons) and there are many other kinds of meson as well.
