How was it discovered?
It was discovered by a group of scientists named Glenn T. Seaborg, Ralph A. James, Leon O.
Morgan and Albert Ghiorso. In 1994. At the University of Chicago metallurgical Laboratory.
Those scientists found the great freedom element Americium.They produced americium by
bombarding plutonium-239, an isotope of plutonium, with high energy neutrons. This
formed plutonium-240, which was itself bombarded with neutrons. The plutonium-240
changed into plutonium-241, which then decayed into americium-241 through beta decay.
