Question Average electron energy in beta decays using G4RadioactiveDecay

Hi,

I am trying to employ G4RadioactiveDecay to model the beta spectra from 40K and other radioisotopes.

For the beta minus decay of 40K the Q value is correctly reproduced when adding the kinetic energies of Ca40, the anti_nu_e and e-. However, the mean electron energy is not met, it deviates by 10 % (~510 keV instead of 560.18 keV). E ave is also not found in the RadioactiveDecay input data, although given in ENDSF.

Does anybody know why is that? Did I miss something? Is the three-body decay algorithm failing here? The same program gives a smaller deviation of about 2.1 % for a 90Sr/90Y decay.

Any help is appreciated.

Regards,

Steffen Greilich
