898:. His value was too high; one conjecture being that this was due to air between the graphite pieces with the nitrogen having high neutron absorption. However the experimental setup involved a sphere of Siemens electro-graphite submerged in water, no air being present. The error in fast neutron cross-section was due to impurities in the Siemens product: "even the Siemens electro-Graphite contained Barium and Cadmium, both ravenous neutron-absorbers." In any event, there were so few staff or groups that they could not repeat experiments to check results, although in fact a separate group at Gottingen, led by Wilhelm Hanle, determined the cause of Bothe's error: "Hanle's own measurements would show that carbon, properly prepared, would in fact work perfectly well as a moderator, but at a cost of production in industrial quantities ruled prohibitive by Army Ordnance". 2387: 44: 890:, Bothe, and up to 6 members from his staff by 1942, worked on the experimental determination of atomic constants, the energy distribution of fission fragments, and nuclear cross sections. Bothe's erroneous experimental results on the absorption of neutrons in graphite were central in the German decision to favor 692:

In May 1914, Bothe volunteered for service in the German cavalry. He was taken prisoner by the Russians and incarcerated in Russia for five years. While there, he learned the Russian language and worked on theoretical physics problems related to his doctoral studies. He returned to Germany in 1920,

It was during 1941 that Bothe had acquired all the necessary funding to complete construction of the cyclotron. The magnet was delivered in March 1943, and the first beam of deuteron was emitted in December. The inauguration ceremony for the cyclotron was held on 2 June 1944. While there had been
