Deuterated Organisms: Cultivation and Uses

Abstract

It is possible, by straightforward means, to generate and detect elastic waves in solids and, to a limited extent, in liquids, up to frequencies of some 1011 cycles/sec. Extensions to even thermal frequencies (1012 to 1013 cycles/sec.) appear feasible. Such mechanical radiation is highly sensitive to any electronic or structural inhomogeneities affecting the interatomic forces, attenuation, or local density. In certain cases this sensitivity renders ultrasonic radiation a particularly useful tool for examining various structural properties and dynamic processes in condensed matter.
