Vor 2 Tagen · The separation facility, using methods developed by Glenn T. Seaborg and a team of researchers at the Met Lab, removed plutonium from uranium irradiated in the X-10 reactor. Information from CP-1 was also useful to Met Lab scientists designing the water-cooled plutonium production reactors for Hanford. Construction at the site began ...

10. Mai 2024 · Glenn Seaborg, a physicist at the University of California, Berkeley, along with chemist Joseph Kennedy and graduate student Arthur Wahl, discovered element 94 that Seaborg named “plutonium” after the planet. The scientists discovered the new element by bombarding uranium with deuterons, the nuclei of the hydrogen isotope ...
Vor 4 Tagen · The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter. It consisted of three parts: two plutonium-gallium hemispheres and a ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during ...
Vor 4 Tagen · Compton’s discovery, known as the “Compton Effect,” earned him the Nobel Prize in physics in 1927. During World War II, as part of the Manhattan Project, a cyclotron at Washington University was used to produce small quantities of the newly discovered element plutonium via neutron bombardment of uranium nitrate hexahydrate.
Vor 3 Tagen · Glenn T. Seaborg, a scientist at Lawrence Berkeley National Laboratory who had been involved in work to make such superheavy elements, had said in December 1997 that "one of his longest-lasting and most cherished dreams was to see one of these magic elements"; he was told of the synthesis of flerovium by his colleague Albert Ghiorso ...
