He went to Berkeley for graduate work where he chose to work with Joseph W. Kennedy and Glenn T. Seaborg. In 1941, Arthur Wahl, Glenn Seaborg, Joseph Kennedy, and Emilio Segrè, building on the earlier work, isolated the daughter of neptunium-239, an element, also of mass 239, that had been predicted theoretically by Louis Turner.
Wahl received his PhD degree in 1942 for the plutonium identification. The papers, related to this work were withheld from publication until after the conclusion of the war.
After receiving his Ph.D. from the University of California, Berkeley in 1942, Wahl was recruited by J. Robert Oppenheimer and Glenn Seaborg to come to Los Alamos in 1943. He was a worker on the Manhattan Project in Los Alamos until 1946, when he joined Washington University in St. Louis.
Beginning in 1952, he was the Henry V. Farr Professor of Radiochemistry; he received the American Chemical Society Award in Nuclear Chemistry in 1966 and retired in 1983. Arthur died in Santa Fe, New Mexico on Mar 6th 2006
