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.

A method for the production of a foam filled target with two regions of different densities is described in this paper. These two different density regions are separated by a 1 μm thick film, with a roughness of 5 μm rms peak to valley. The two regions are filled with a homogeneous, different density foams. These targets were designed to investigate the Richtmyer-Meshkov instability in the plasma region. The production of these targets using the in-situ polymerization technique is described. Several approaches for the production of these targets are examined. Triacrylate foams with densities of 40 mg cm−3 and 200 mg cm−3 were used in the targets.
