The theory of collisional depolarization of spectral lines by atomic hydrogen (Derouich et al. [CITE]) is extended to d atomic levels. Depolarization rates, polarization and population transfer rates are calculated and results are given as a function of the temperature. Cross sections as a function of the effective quantum number for a relative velocity of 10 are also given together with velocity exponents λ, if they exist, with the assumption that the cross section varies with velocity as . A discussion of our results is presented.
Key words: Sun: atmosphere / atomic processes / line: formation / polarization
