	Yoshio Nishina - Wikipedia, the free encyclopedia
		Yoshio Nishina (仁科芳雄) (December 6, 1890–January 10, 1951) was a Japanese physicist.
		He co-authored the well-known Klein-Nishina Formula, and the Nishina crater on the moon is named in his honor.
		During World War II he was the head of the Japanese atomic program, which was alleged to have detonated a nuclear weapon during testing in 1945.

	Stories from RIKEN's 88 Years
		It was in 1946, during the turmoil that followed the end of the war, that Yoshio Nishina, the fourth Director of RIKEN, undertook the task of making RIKEN fully self-reliant.
		Nishina knew that the United States had begun cheap steel production using large amounts of oxygen during the war, and he judged that this technology would be useful given the dire state of Japan's energy supplies.
		In 1947, Yoshitoshi Oyama's lab, together with the Nishina, Tsuji, Ebihara, and Kuroda labs, began their collaborative research, using funds obtained from RIKEN and a grant from the ministry of trade and industry.

		Supposedly, Nishina thought that the warhead would go off if the two subcritical warhead components were compressed in 1/20th to 1/30th of a second, and not the 1/200th to 1/300th of a second that was truly necessary.
		The text was handwritten by a military officer who interviewed Yoshio Nishina, a scientist who headed the atomic bomb development team at the Riken Institute, which still exists in Saitama, just north of Tokyo.

		In 1937, Yoshio Nishina, a physicist at RIKEN and pioneer of quantum physics in Japan, led the development of the worldâs second cyclotronâ”albeit a small one with a magnet pole of 65 centimeters in diameter.
		Nishinaâs team completed construction of a bigger cyclotron (150 cm diameter) in 1943, and, in the following year, successfully tested a powerful beam of deuterons, which produce more energy in fusion reactions than protons.
		Devastated, Nishina nevertheless continued on to become the fourth president of RIKEN after it was dissolved and reorganized in 1948.

	THE JAPANESE A-BOMB
		Nishina died in 1951 and there is no known account by him of his wartime activities.
		Nishina, Sagane, and some others were clearly world class physicists; but Japanese physics included a "comparatively large number of nonadvanced fields." Scientists Suggest Project The scientists themselves initiated atomic bomb research in September 1940.
		According to one account, the morning after the bomb was dropped, Nishina was summoned and asked first whether the bomb could have been atomic and "whether Japan could have one in six months." Nishina was flown over Hiroshima on 8 August.

		In March 1922 in Cambridge, Nishina, aged 31, met Niels Bohr, aged 36, who had also studied under Rutherford and was then an up-and-coming physicist at Copenhagen University.
		In the 1920s, Yoshio Nishina had worked under Bohr with top young physicists from countries around the world, and participated in the creation of quantum mechanics.
		With Nishina as interpreter, Bohr gave ten lectures around the country, and attended numerous debates and dinners.

	Historian's Corner: Japan's A-Bomb - 39th BG (VH)
		The central figure in Japan's atomic research was Dr. Yoshio Nishina, a brilliant scientist who was highly patriotic.
		In 1931 Dr. Nishina received his own laboratory at the Institute of Physical and Chemical Research.
		Nishina knew that building a uranium bomb was possible and fearful that the Americans were already at work on such a bomb.

		The lieutenant general who ran the Aviation Technology Research Institute of the Imperial Japanese Army, Takeo Yasuda, followed the scientific literature on the potential for large energy releases due to nuclear fission, and ordered the first study of the subject in April 1940 in Japan.
		Nishina worked on this problem at his research institute, the Riken, equipped with a small staff, a small cyclotron, and marginal funding beginning in April 1941.
		The Japanese Imperial Army project under Dr. Nishina continued however, and was later supplemented by the Imperial Navy's second nuclear program, this one financed by the Fleet Administration Center.

	Bulletin 22 - Influence of Hiroshima and Nagasaki on Scientists in Japan
		The Japanese Government and military sent scientists to Hiroshima to determine whether the bomb that was used was an atomic bomb.
		Yoshio Nishina, a physicist from the Physics and Chemistry Laboratory, was one of those scientists.
		At the second general assembly of the SCJ, Dr. Yoshio Nishina, Vice President of the SCJ, who had worked for the development of the atomic bomb during the war at the request of the army, proposed the following statement: "The Science Council of Japan longs for peace.

		As indicated by a previous post, Yoshio Nishina was indeed the top Japanese atomic physicist during the War years.
		Although his research was initially on a modest scale, Nishina nevertheless managed to produce 1) a working thermal diffusion separator, 2) a small uranium ore-processing plant, and 3) a small amount of uranium hexaflouride gas---the first step along the gas-diffusion separation route that was eventually so important to the United States.
		Yoshio Nishina himself published a paper on the subject prior to Japan's declaration of war against the West.

		Especially valuable to the historian of science are his discussions of scientific relationships with his colleague Sin-Itiro Tomonaga, with his teacher Yoshio Nishina, and with his students (who later became his collaborators): Sakata, Taketani, and Kobayashi.
		The Story ends with the writing of his first scientific paper in English, being the birth of the meson theory of nuclear forces.

		Tomonaga was born in Kyoto and graduated from Kyoto University in 1929.
		Upon his graduation, Tomonaga obtained employment at the Institute of Physical and Chemical Research in Tokyo under Yoshio Nishina and later, from 1937 to 1939, Tomonaga worked under Werner Heisenberg in Leipzig.
		It was in Leipzig where Tomonaga wrote his Ph.D. Upon his return to Tokyo, Tomonaga began to research mesons and was able to develop a coupling theory to explain the structure of the proton and neutron.

		Problems anticiptated by the Japanese Naval Technolgical Research Institute and it's committees, and Yoshio Nishina, concluded that assuming the location, mining, and extraction of suitable quantities of Uranium could be accomplished...it would require one tenth of Japan's total electrical output to achieve any separation and would consume ONE HALF of the nations' available copper supply.
		They figured they were at least 10 years away from any real developments and instead put more of their energies, and resources, into more pressing areas like radar.
		Nishina determined that only gaseous diffusion had any chance given resouce limitations, but was unaware that this method had been demonstrated inadequate by Frisch's secret research so he pursued it.

		Some historians have questioned the reliability of the transcripts, as Heisenberg probably knew that he was being monitored; others believe that his shock could not have been feigned.
		It has been pointed out that Japanese physicist Dr. Yoshio Nishina did manage to correctly calculate the critical mass of orlistat xenical required to sustain a chain reaction.

		Next year will be the seventieth anniversary of the start of operation of the first Japanese cyclotron, built by Yoshio Nishina.
		When used together with the new superconducting radioisotope beam separator, it will open the door to a realm of research on unstable nuclei that was previously thought unattainable.
		Carrying on Nishinaâs intention, it will also be used for medicine, agricultural science, and other fields.

		One of the films, found in the research office of the late Japanese physicist Yoshio Nishina in Tokyo, turned fl from radiation following the atomic bomb attack on Hiroshima, proving to military officials that the damage was not from an ordinary bomb, the Mainichi Shimbun reported Thursday.
		Ryohei Nakane, 84, a former scientist at Riken Institute, found the films while organizing data from the office after earthquake reinforcement work last year.
