I'm trying to figure out the energy balance for the $\beta^+$ and electron capture (ec) decay modes of Al-26. According to the decay data at http://www.nndc.bnl.gov/nudat2/decaysearchdirect.jsp?nuc=26AL&unc=nds and http://www.nucleide.org/DDEP_WG/Nuclides/Al-26_tables.pdf, the endpoint energy for the $\beta^+$ mode is 1173.42 keV, which, if I understand it correctly, would correspond to a neutrino-free decay as all the energy and momentum are balanced by the positron. However, there seems to be no energy level of the daughter nuclide Mg-26 that corresponds to a gamma ray of 2830.72 keV, which would be necessary to arrive at the ground-level energy difference of 4004.19 keV between Al-26 and Mg-26.
By contrast, the energies tabulated for ec, 1065.78 and 2195.47 keV, correspond exactly to the observed gammas with 2938.41 and 1808.72 keV, respectively, that are required to bring the excited daughter Mg-26 into its ground state.
What am I missing? I would have expected that the $\beta^+$ and the ec feed the same energy levels of Mg-26, especially as I don't see separate gamma energies tabulated for both modes.
