Life

Hoffman studied at Iowa State College with a bachelor's degree in 1948 and received his doctorate there in 1951 under Don S. Martin with the thesis High specific radioactivities of cobalt, platinum and iridium from photonuclear reactions . During this time she was an assistant in the Ames Laboratory of the Atomic Energy Commission (AEC). Then she was 1951/52 at the Oak Ridge National Laboratory and 1952 to 1971 chemist at the Los Alamos National Laboratory . There she became head of the Isotope and Nuclear Chemistry Division in 1981 . In 1984 she became Professor at the University of California, Berkeley and Head of the Heavy Element Nuclear & Radiochemistry Group at the Lawrence Berkeley National Laboratory . She was also founding director of the Seaborg Institute for Transactinium Science in 1991. In 1996 she retired.

She is an expert in the chemistry of transuranic elements and transactinides and a leading international expert in spontaneous fission . She was one of those who confirmed the discovery of the element seaborgium (atomic number 106) and studied these and other transactinoids (such as rutherfordium , hahnium ) with a technique that she helped to develop at the 88-inch cyclotron in Berkeley.

She also studied the spread of radioactive nuclides in the environment and was on the National Academy of Sciences Advisory Committee on Radioactive Waste.

She has been married to the physicist Marvin M. Hoffman since 1951 and has a son and a daughter.

Honors and memberships

She is a Fellow of the American Association for the Advancement of Science and the American Physical Society as well as the Norwegian Academy of Sciences and, since 1998, the American Academy of Arts and Sciences . She is an honorary doctorate from the University of Bern (2001).
