Description: Papers of Robert D. Hill (1913- ), professor of physics (1947-65), including correspondence, manuscripts, reprints, copies of requisitions and related material concerning research in nuclear spectroscopy and elemental particle physics and atmospheric and space electricity; teaching physics courses and graduate students; publications; Physics Library; financial support; purchase of equipment and materials; comments on preprints, reprints and research grant proposals; professional meetings; examination and placement of graduate students and a 1953-54 sabbatical leave spent at Brookhaven National Laboratory where Prof. Hill's interests shifted to the study of K particles and Tau and Pi mesons in high energy physics. Receiving his D.S. at Melbourne in 1945, Prof. Hill specialized in the analysis of irradiated tellurium, berylium, samarium, cerium and gold. He exposed emulsion plates in balloon flights and wrote on long-lived tellurium isomers. On sabbatical in London in 1960-61, he worked in high energy physics with the nuclear emulsion and bubble chamber groups. After 1961, he began work on lightning research.
