Absorption spectrum in Te

I am trying to build an absorption spectrum for CdTe and it did not give me the anticipated spectrum. Then I tried to build one for Te alone. It gave me this spectrum. I used QGSP_BERT and Penelope physics lists, both of them gave similar results. Also added /process/em/fluo true
/process/em/fluoBearden true in UI command (macro file).

Why am I not getting the k-peaks at the right energies?
