Optical Oscillator Strengths of Hydrogen Chloride in theEnergy Region of 5.5-20eV

Absolute optical oscillator strength density (OOSD) spectrum of HCl in the valence shell energy region of 5.5-20 eV has been determined by the high resolution fast electron energy loss spectrometer (EELS). The optical oscillator strengths for the broad A¹ + 1³Σ⁺ dissociation peak and the discrete transitions of b³(v' = 0), C¹(v'= 0,1,2) and M¹(v'= 0) are reported.
