Abstract: In the framework of the quantum defect theory, we have studied the photofragment yield spectrum for F- from the F2 ion\|pair production with the multiple\|scattering self\|consistent field method and the theoretical time\|dependent wave\|packet dynamics method. Based on our calculation, the profiles were clear assigned and the calculated intensities were in fair agreement with the experiment. We elucidated the prospect of the study on the super\|excited state.
