The critical point energies, Eo, E1 and the Lorentz broadening parameter, Γ, for boron doped p-type silicon were obtained by electrolyte-electroreflectance (EER) at 297K and electron beam electroreflectance (EBER) at 297K and 88K. Electron irradiated samples for fluences of 1014 and 1016 e-/cm2 were compared to the samples before irradiation. The value of the low energy weaker structure, Eo and the higher energy main structure, E1 are obtained by the synthesis of two Lorentz line shapes to fit the experimentally obtained composite spectra. The values as determined by EER were all found to increase with radiation as expected. The values for Eo as found by EBER were consistent with those of EER but those of E1 were not.
