Goodman, F.O. (author)
A simple n-dimensional lattice model is used and the atomic motions both normal and tangential to the lattice surface are discussed. Two different problems are considered and related; these are (i) the tangential and normal response functions of the lattice atoms and (ii) their tangential and normal thermal motion. The results are highly...

A new classical theory of thermal energy exchange between gases and solid surfaces is proposed. The theory is a generalisation of that proposed in paper III of this series; it applies to both light and heavy gases and to both small and large transfers of energy, including enrrgy transfers sufficiently large to result in the trapping of a gas...

A first attempt is made to give a statistical calculation of the velocity distribution function of a re-emitted gas beam for an arbitrary velocity distribution of a gas beam incident on a solid surface. Exact formulae in closed form are presented for some special cases. The model used is one-dimensional, and the theory is entirely qualitative in...

With the use of operator techniques a unified treatment is given of the harmonic oscillator subject to an applied force which is an arbitrary function of time. Few of the results are new, and most have appeared piecemeal in papers devoted to other topics and using a wide variety of mathematical methods. Numerical methods tor the calculation of...

A new classical theory of thermal energy exchange between gases and solid surfaces is proposed. A perturbation method is used and, because of the inherent errors in this method, the theory is restricted to light gases and small thermal accommodation coefficients. Realistic interaction potentials of the Morse type between the gas atoms and the...

The lattice dynamics of simple cubic lattices are studied from the point of view of thermal accommodation coefficient theory. An n-dimensional semi-infinite lattice model is devised and is used as a model of a solid surface. For the cases of one-, two- and three-dimensional lattices it is shown in detail how the motion of such a lattice model...
