INVERSE POWER-SERIES FITTINGS OF TEMPERATURE-DEPENDENCE OF THERMAL-DIFFUSION FACTORS BETWEEN 2 COMPONENTS OF HYDROGEN ISOTOPE MOLECULES

Temperature dependence of thermal diffusion factor of binary isotope m ixture of hydrogen with one tracer level component alpha(Tab)([A\simil ar or equal to 1.0) was numerically fitted as an inverse power series or temperature from 25 to 1,500K so that relative errors are less than 0.01 to approximations of the rough estimate of thermal diffusion fac tor which was previously reported. Composition dependence of thermal d iffusion factor was expressed as a linear function of the c-th power o f the mole fraction.
