Title: Tube contains first sample of americium
Description: The triangle in the glass tube contains the world's first sample of americium, produced in the 60-inch cyclotron in 1944. Seaborg, Albert Ghiorso, James Kennedy, B. B. Cunningham, and others elaborated the rich and varied chemical properties of the actinide elements. They continued work begun during the war at Chicago where their identification of americium (element 95) and curium (96) among the products of plutonium bombarded in the Berkeley and St. Louis cyclotrons confirmed the actinide concept, the existence of a series of heavy homologues of the rare earth elements. (The preceding information was excerpted from the text of the Fall 1981 issue of LBL Newsmagazine.)
