Description

Atomic interaction potentials were derived from diatomic-molecule spectra and from quantum chemistry and were used to calculate collisional cross sections, viscosities, thermal conductivities, and the second group integrals for beryllium, magnesium, calcium, and strontium vapors at 800-2000 K. Large discrepancies occurred between calculated transport coefficients for magnesium and viscosity and conductivity measurements which substantially exceeded the overall errors in the calculations and measurements. It is shown that these discrepancies cannot be explained from inaccuracies in the raw data or calculation methods
