Coauthored a fractional quantum Hall effect experiment using shot noise to measure tunnelling carriers with electric charge $e/3$ at filling factor $1/3$. ^[ref]

A physicist associated with research on laser cooling. His NIST account explains how measured atomic temperatures fell below the limit predicted by a simple Doppler cooling model. The discrepancy led to a more detailed explanation involving atomic internal states and spatially varying light polarization, including Sisyphus cooling. The episode shows why measuring the velocity distribution was essential: a model adequate for slowing an atomic beam did not capture all the processes operating in an optical cooling experiment.^[ref]

Coauthored the reactor electron antineutrino confirmation. Halving the target proton density halved the signal, supporting its interpretation as inverse beta decay.^[ref]

Coauthored the electron antineutrino experiment using coincidence counting in layered scintillators, with prompt positron annihilation followed by delayed neutron capture in cadmium.^[ref]

Coauthored the reactor electron antineutrino confirmation using inverse beta decay. Prompt positron annihilation and delayed neutron capture supplied a distinctive paired signal.^[ref]

Coauthored nuclear magnetic resonance measurements of liquid helium-3 in which a shifted resonance appeared below about $2.7$ mK; near $2$ mK it disappeared and the liquid absorption dropped to roughly half. ^[ref]

Coauthored observations of electron-muon pairs with missing energy in electron-positron annihilation. Their analysis required at least two unobserved particles in each event.^[ref]

A physicist whose neutron scattering research investigated condensed matter, including solid buckminsterfullerene. Neutrons provide structural information that complements a material’s bulk properties. He also developed an exposition of neutron diffraction from powdered samples for students and other nonspecialists, making the connection between measured scattering patterns and material structure more accessible.^[ref]

Coauthored tests of multiwire proportional chambers in which wires spaced $1\mathrm{mm}$ apart operated as independent proportional counters, enabling electronic localization of charged-particle tracks.^[ref]
