The three lowest spectral moments of the collision induced absorption (CIA) spectra of H2-He pairs have been computed from first principles for temperatures T from 18 to 7000 K for a number of hydrogen overtone and hot bands involving vibrational quantum numbers nu = 0, 1, 2, 3 yields nu-prime = 0, 1, 2, 3. The data are given in a form suitable for the computation of CIA spectra of H2-He as function of frequency and temperature, using simple computer codes and model line shapes. The work is of interest for the spectroscopy of the atmospheres of the outer planets and of stars that contain neutral molecular hydrogen and helium (late stars, white dwarfs, and Population II stars) in the infrared and visible region of the spectrum. 13 refs.
