【 摘 要 】

Synopsis We use R-matrix method to study the near threshold (17.5eV-20eV) photoionization of neutral fluorine atom and obtain total photoionization cross sections in 3P to 1D range. The theoretical calculation results fit the experimental results better after we consider core-valence electron correlation.
