Absolute Generalized Oscillator Strength Profiles of Rydberg Transitions in C₂F₆

Absolute generalized oscillator strengths (GOSs) for the two Rydberg excitations at 12.1 eV and 13.5 eV in C₂F₆ have been determined as functions of energy loss and momentum transfer (K) at impact energy of 2.5 keV. The GOS profiles for these two Rydberg transitions to 3 p Rydberg orbital have the characteristic dipole-dominated shapes with a strong maximum at K = 0.
