Neutron-Induced Radioactivity of Tungsten

Behavior of tungsten under irradiation and plasma interaction

“…Within this period there were still many publications on light bulb applications ( [42] provides one of the first reviews) and surface chemistry, but also on tungsten deposits, ore and production. Also during that time, the first articles on neutron interactions with tungsten (activation analysis, isotopes, decay, neutron resonances) were published [43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58]. Since 14 MeV neutrons play an important role in nuclear fusion, it is interesting that for the first fission cross-section studies on tungsten [59] a neutron source was used, which utilized the T+DHe+n reaction -the Los Alamos Van de Graaff.…”

Discovery of the tungsten isotopes

“…In 1940, Minawaka reported the discovery of 187 W together with the discovery of 185 W in Neutron-Induced Radioactivity of Tungsten [30]. Pure metallic tungsten powder was irradiated with slow and fast neutrons produced in nuclear reactions in the Tokyo cyclotron.…”
