Bremsstrahlung radiation for low energy electrons

I’m interested in bremsstrahlung spectra of electrons (E<70MeV) emerging from their interactions with tungsten. Which of two physics list of electromagnetic interactions is better to use for this purpose: from Hadr06 example or from TestEm18 example ?

I would suggest to use a physics list with G4EMStandards_option4 or G4EMPenelope to model the bremsstrahlung. Probably you may want to keep the fluorescence on.
