By introducing the converting method from electron-impact ionization cross sections to rate coefficients through using a semi-experiential formula, we try to probe a semi-experiential formula for converting the photo-ionization cross sections into photo-ionization rate coefficient. It’s found that photo-ionization rate coefficient is direct proportion to photo-ionization cross sections, the rate S is related with light resource.
