Which formula or equation can relate photo-ionization cross section to photo-ionization rate?

Hello,

I don't know about relation of cross section to the rate, but there is a relation of the photoionisation probability to the rate. Perhaps you can derive from that what you need.

See Eq 5 in the attached paper
