(1977) is noteworthy: it uses the method of dimensional continuation and proper time representations, and with these methods, he computed the unique gravitational anomaly for scalar fields and the anomaly for vector fields (Brown & Cassidy 1977). Brown and collaborators computed the energy–energy correlation in electron–positron annihilation (Basham et al. 1978), which provides one method of measuring the strong interaction QCD coupling constant. Brown was the first to compute the stress–energy tensor between conducting planes (Brown & Maclay 1969). The stress tensor evaluated on a plane yields the Casimir force. He was the first to exhibit the classical limit of the hydrogen atom (1973). He constructed large-quantum-number wave packets that slowly spread while moving in circular orbits. At the University of Washington, Hans Dehmelt captured single charged particles in very stable orbits in a Penning trap. This arrangement, called geonium, enabled measurement of the magnetic moment of the electron with exquisite precision for which Dehmelt won the Nobel Prize. Brown became fascinated with this new experimental procedure and with coworkers wrote many papers investigating the detailed workings of geonium. His work culminated in a long review article (Brown & Gabrielse 1986) that has become a handbook for other experimenters who use a Penning trap. Brown also investigated plasma effects on nuclear fusion (Brown & Sawyer 1997), wrote a paper applying field theory to plasma physics (Brown & Yaffe 2001), obtained the non-leading corrections in plasma stopping power (Brown et al. 2005), and provided an effective field description for deuterium-tritium fusion (Brown & Hale 2014). Publications Book Cited articles Professional society activities Brown served on many committees of the American Physical Society and was the first academic Editor of Physical Review D. During his tenure (1987-1995), he was instrumental in incorporating author-prepared electronic manuscripts into the journal's editorial and publishing process, and he conceived and promoted an early version of the electronic status inquiry system for authors.
