Theoretical calculation of transition probabilities in neutral fluorine

The weakest bound electron potential model (WBEPM) theory is used to calculate transition probabilities for individual lines in neutral fluorine, for which transition probability data are scarce. A coupled equation concerning energy ε and the radial expectation value 〈r〉 of the weakest bound electron is proposed to determine the parameters used in the calculation of transition probability. The accuracy of present results has been tested from comparisons with the most theoretical or experimental results presently available.
