Quantum Theory of Gas-Surface Interactions.
Abstract
The purpose of this research program is to develop a better understanding of how gases at thermal energies interact with metallic surfaces. Such an understanding should not only help to explain a large body of data obtained in experimental investigations on the fundamental properties of surfaces but may also provide a useful computational tool for practical applications such as the computations of drag coefficients and heat exchange parameters of high-altitude, high-speed aircraft. A formalism was developed to permit calculations of energy and momentum exchange probabilities for gases impinging on bare metallic surfaces. A mixed classical and quantum-mechanical approach was used and the basic technique involved the application of two-step time-dependent perturbation theory. The calculation resulted in an expression for the probability of energy transfer which included all multiphonon events.
