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 
. 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 
is given together with an exponent λ, if it exists, with the assumption that the cross section varies with velocity as 
. The general trends of depolarization rates, polarization transfer rates and population transfer rates are discussed.
Key words: Sun: atmosphere / atomic processes / line: formation / polarization
