General Comments:

2005Mo28 reported two excitation energies, 3095 keV and 3339 keV, in the preliminary analysis of 26Si+p elastic resonance.

2002Zh30, 2001Fa15, 2001Fa23: Evidence of a proton halo reported from measured interaction cross section of 27P with carbon, 2151(123) mb at 30 MeV/u, compared to a series of measured interaction cross sections.

1998Na34: Measured proton knockout reaction cross section of 27P on 9Be, 74(11) mb, and reported a 26Si ground state population cross section of 22(8) mb.

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔQ(β-)=400(syst), ΔS(n)=197(syst) (2011AuZZ)

Q-value: Q(β-)=-18260 200(syst), Q(α)=-9910 30 (2003Au03)
