Abstract
The theory of collisional depolarization of spectral lines by atomic hydrogen (Derouich et al. 2003a; Derouich et al. 2003b) is extended to f-atomic levels (l=3). Depolarization rates, polarization and population transfer rates are calculated and results are given. Each cross section as a function of the effective quantum number for a relative velocity of 10 km s-1 is given together with an exponent lambda, if it exists, with the assumption that the cross section varies with velocity as v-lambda. The general trends of depolarization rates, polarization transfer rates and population transfer rates are discussed.
