Darleane C. Hoffman, transuranium element pioneer, dies at age 98
Hoffman
Nuclear chemist Darleane D. Hoffman, who was renowned for her research on transuranium elements that advanced the understanding of nuclear fission, died on September 4 at her home in Menlo Park, Calif. She was 98.
Iowa origins: Hoffman was born on November 8, 1926, in Terril, Ia. She attended Iowa State University, where she earned a bachelor’s degree in chemistry in 1948 and a doctorate in physical (or nuclear) chemistry in 1951. She then began working as a chemist at Oak Ridge National Laboratory.
Los Alamos research: In 1953, Hoffman began a research position at Los Alamos National Laboratory, where she conducted pioneering work on spontaneous fission. She served as the lab’s first female division leader in charge of the Chemistry and Nuclear Chemistry Division.

Miley et al. and, independently, Mizuno et al. claim to have observed nuclides produced in Ni (Z = 28) when an electrolytic light-water cell is used. Miley et al. use thin layers of Ni (5 × 10-6 cm) and claim that the effect is reproducible. The secondary nuclides are distributed in a wide range of Z and A and show nuclides with Z < 28 and accumulations at Z = 48 and 78. If the nuclides at Z = 48 and 78 are Ni-Ni fusion, they can be produced only when the original Ni nuclei gain sufficient kinetic energy to overcome the Ni-Ni repulsive Coulomb barrier.The foregoing data are discussed in terms of current physics. In particular, it is assumed that the gain of kinetic energy derives from an impulsive increase of absolute nuclear binding energies of Ni due to a high rate of capture of orbital electrons and consequent almost instantaneous multiple p → n transitions. Under this hypothesis, neutrino emission should be detected during nuclear transmutation.
