Abstract
Accurate theoretical expressions for momentum and temperature-slip coefficients for monatomic gases with arbitrary accommodation at the surface are derived by applying a variational technique to the full linearized Boltzmann equation. In the jump regimes, the use of these expressions appears preferable to the use of the previous results based on mean-free-path theory or numerical methods. As an example, a correction in the reported values of accommodation coefficients is suggested.Keywords
