Zusammenfassung: | Quantal scattering theory has been applied to calculate the coefficients of viscosity and thermal conductivity of atomic hydrogen from 1 to 400 °K on the basis of the accurate interaction potentials of Dalgarno & Lynn. The wave equation has been integrated numerically and phase shifts with their appropriate multiples of π are presented for L = 0(1) 35. The effect of the identity of the protons on the viscosity cross-sections has been investigated. The quantal cross-sections have been compared with the classical values of Dalgarno & Smith and with values estimated by the empirical method of Hirschfelder & Eliason. Correction terms have been evaluated for obtaining the second approximation to the coefficient of viscosity in the Chapman-Enskog formulation. |
