摘要：

The theory of collisional depolarization of spectral lines by atomic hydrogen (Derouich et al. 2003) is extended to d (l = 2) 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 km s(-1) are also given together with velocity exponents lambda, if they exist, with the assumption that the cross section varies with velocity as v(-lambda). A discussion of our results is presented.
