There are several spaces in the Periodic Table between plutonium (element 94) and einsteinium (element 99). But by 1952 these had already been filled by scientists at Berkeley, using the cyclotron to bombard heavy nuclei with particles that, when captured, increased the nuclear mass. In 1944 Glenn Seaborg, Albert Ghiorso, and Ralph James made elements 95 and 96 this way. Kept secret until after the war, they were respectively called americium and curium.

Glenn Theodore Seaborg (1912-1999), together with Stanley Gerald Thompson (1912-1967) and Albert Ghiorso ( 1915). The bombardment of americium-241 with alpha particles led to element 97 with atomic mass number 243. The enrichment involved chemical methods, as the properties of the element were assumed to be analogous to those of the lanthanides. 

Curium (Cm, [Rxi 5f16dxls2), named after the scientists Marie and Pierre Curie. Discovered (1944) by Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso. Silvery white metal.

Seaborgium - the atomic number is 106 and the chemical symbol is Sg. The name derives from the American chemist Glenn Theodore Seaborg , who led a team that first synthesized a number of transuranium elements. The element Seaborgium was first synthesized by American scientists from the University of California lab in Berkeley, California imder Albert Ghiorso, who used the nuclear reaction Cf ( 0,4n) Sg. The longest half-life associated with this unstable element is 21 second Sg. 

Glenn T. Seaborg and his colleagues, S. G. Thompson and A. Ghiorso continued to use the cyclotron in their laboratory located at the University of Galifornia, Berkeley, to create new transuranic elements. Between 1949 and 1950, they produced their fourth artificially... 

Albert Ghiorso and his team of chemists that included Glenn T. Seaborg, Stanley G. Thompson, Bernard G. Harvey, and Gregory R. Ghoppin bombarded atoms of einsteinium-253 with hehum ions in the cyclotron at the University of California at Berkeley. This resulted in a few atoms of mendelevium-256, which is one of the isotopes of mendelevium plus a free neutron. 

Three groups had roles in the discovery of nobelium. First, scientists at the Nobel Institute of Physics in Stockholm, Sweden, used a cyclotron to bombard Cu-244 with heavy carbon gC-13 (which is natural carbon-12 with one extra neutron). They reported that they produced an isotope of element 102 that had a half-life of 10 minutes. In 1958 the team at Lawrence Laboratory at Berkeley, which included Albert Ghiorso, Glenn Seaborg, John Walton, and Torbjorn Sikkeland, tried to duplicate this experiment and verify the results of the Nobel Institute but with no success. Instead, they used the Berkeley cyclotron to bombard cerium-...

Californium was discovered in 1950 by a research team at the University of California at Berkeley. The team—made up of Glenn Seaborg (1912— 1999), Albert Ghiorso (1915—), Kenneth Street Jr. (1920—2006), and Stanley G. Thompson (1912—1976)—named the new element after the state of Galifornia.
