Remembering ANS member Gil Brown
Brown
The nuclear community is mourning the loss of Gilbert Brown, who passed away on July 11 at the age of 77 following a battle with cancer.
Brown, an American Nuclear Society Fellow and an ANS member for nearly 50 years, joined the faculty at Lowell Technological Institute—now the University of Massachusetts–Lowell—in 1973 and remained there for the rest of his career. He eventually became director of the UMass Lowell nuclear engineering program. After his retirement, he remained an emeritus professor at the university.
Sukesh Aghara, chair of the Nuclear Engineering Department Heads Organization, noted in an email to NEDHO members and others that “Gil was a relentless advocate for nuclear energy and a deeply respected member of our professional community. He was also a kind and generous friend—and one of the reasons I ended up at UMass Lowell. He served the university with great dedication. . . . Within NEDHO, Gil was a steady presence and served for many years as our treasurer. His contributions to nuclear engineering education and to this community will be dearly missed.”

Exact elementary functions for the value and first two lethargy derivatives of the collided neutron flux at source lethargy have been derived previously for a monoenergetic plane source in hydrogen, and the results have been used both to test calculational methods and to synthesize an elementary function for the entire spatially dependent slowing down distribution. In this Note, the exact elementary functions at source lethargy are generalized to allow: (a) any number and thicknesses of homogeneous slabs with faces parallel to the source plane, (b) each slab to be composed of any mixture of isotopes with arbitrary energy-dependent elastic scattering and absorption cross sections, and (c) any number of equally spaced cosine-weighted source planes.
