Atomic bomb research notes found at Kyoto Univ.
The Yomiuri Shimbun
Notebooks used by a researcher working on development of an atomic bomb at Kyoto Imperial University, now Kyoto University, during World War II have recently been discovered.
As sources that shed light on Japans wartime atomic bomb research, the three notebooks found at the Radioisotope Research Center at Kyoto University are particularly valuable because materials concerning such development work at the university were confiscated by U.S. forces immediately after the end of the war.
The notebooks belonged to Sakae Shimizu, who later became a professor emeritus at Kyoto University. He died in 2003. Various documents are inserted into the notebooks. Akira Masaike, 80, a professor emeritus of the university who specializes in particle physics, confirmed that the notebooks were stored at the center when he visited there in May.
The notebooks have Ultracentrifuges and 2604th year of the Imperial reign written on their covers. They are believed to have been used in October or November of 1944.
