Circa 1942, Stetter led a group of six physicists and physical chemists in measuring atomic constants and neutron cross sections, as well as investigating transuranic elements.

Neutron howitzers were used by Otto Hahn, Fritz Strassman and Lise Meitner in 1938 to bombard uranium nuclei with neutrons in the hopes of making transuranic elements.
23.
Similarly, American military planners trying to build powerful bombs in the 1930s would have laughed at suggestions that they finance research into anything so arcane as transuranic elements.
24.
The harsh planet is home to the " fierce and perverse " Darsh, who mine " black sand ", stable transuranic elements of atomic number 120 or greater.
25.
This could either be viewed as good ( generate more fuel ) or can be viewed as bad ( generation of more " radiotoxic " transuranic elements ).
26.
During their long reaction period about 5.4 tonnes of fission products as well as 1.5 tonnes of plutonium together with other transuranic elements were generated in the uranium ore body.
27.
In the 1980s, Sodern has developed its civil neutron activity and designed neutron generators ( TN26 then GENIE36 ) used by radioactive waste reprocessing plants for the measurement of transuranic elements.
28.
This is a stable transuranic element of the kind predicted during the 1970s based on the theory of an Island of stability for elements of atomic number 114, 120 and 126.
29.
In the PYRO-B processing of such fuel, an electrorefining step is used to separate the residual transuranic elements from the fission products and recycle the transuranics to the reactor for fissioning.
30.
She soon made good friends with Harold Urey and Enrico Fermi, who arrived at Columbia in 1939 . Fermi asked her to investigate the valence shell of the undiscovered transuranic elements.
