From Wikipedia, the free encyclopedia

Ausonium (atomic symbol Ao) was the name assigned to the element with atomic number 93, now known as neptunium. It was named after a Greek name of Italy, Ausonia.[1]

The same team assigned the name hesperium to element 94, after Hesperia, a poetic name of Italy. [2]

The discovery of the element, now discredited, was made by Enrico Fermi and a team of scientists at the University of Rome in 1934. In the same year Ida Noddack already prented alternative explanations for the experimental results of Fermi.[3] Following the discovery of nuclear fission in 1938, it was realized that Fermi's discovery was actually a mixture of barium, krypton, and other elements. The actual element was discovered several years later, and assigned the name neptunium.[2]

Fascist authorities wanted one of the elements to be named littorio after the Roman lictores who carried the fasces, a symbol appropriated by Fascism.[2]
