||Carson Dunning Jeffries (b. March 22, 1922) was an American physicist. The National Academies Press said that Jeffries "made major fundamental contributions to knowledge of nuclear magnetism, electronic spin relaxation, dynamic nuclear polarization, electron-hole droplets, nonlinear dynamics and chaos, and high-temperature superconductors." He was noted for being the first to observe the isotropic spin-spin exchange interaction in metals (also known as the Ruderman-Kittel interaction). He also discovered methods for the dynamic nuclear polarization by saturation of forbidden microwave resonance transitions in solids. He also discovered the existence of giant electron-hole droplets in semiconductors.
