T,p-Dependence of the self-diffusion and spin–lattice relaxation in fluid hydrogen and deuterium
Abstract
Self-diffusion coefficients D were studied for fluid hydrogen and fluid deuterium at pressures up to 200 MPa and in the temperature range 171–372 K by the spin echo method. Spin–lattice relaxation times of both nuclei were measured in the same p,T range. The diffusion coefficients D are described by the rough hard sphere (RHS) model invoking the rotation translation coupling parameter A
