Guy White

Dr Guy White is distinguished for experimental contributions to knowledge of the transport properties, thermal capacities and thermal expansions of solids. His studies of electrical and thermal conduction of metals, alloys, semi-conductors and solidified inert gases have revealed the contributors of lattice and electrons and the roles of defects and mutal interaction of lattice waves. More recently he has applied the electrical capacitance technique in pioneering measurements down to 1 - 2oK of the very small thermal expansions of a wide range of metals, alkali halides, diamond-structure elements, glasses, anisotropic crystals, superconductors and other materials. This has provided the first observations of the free-electron contribution to thermal expansion, and yielded basic data on anharmonic forces in the crystal lattice. Dr White is also responsible for the first determination of magnetostriction in palladium and other paramagnetic elements, giving information about magnetic exchange forces. He is an outstanding experimenter, and his book on "Experimental Techniques in Low Temperature Physics" is the standard text in this subject.
