Abstract The absolute optical oscillator strength density spectrum of HBr in the valence shell energy region of 4.5-20 eV has been determined by a high-resolution fast electron energy loss spectrometer. The optical oscillator strengths for the broad a3II + A1II dissociation peak and the discrete transitions of 3II1(v = 0) and C1II(v '= 0,1,2) are reported. It has been manifested clearly that the optical oscillator strengths of some transitions for the previous photoabsorption method are subject to severe line-saturation effects.
