General Comments:

Theoretical works:

2006Ko02: α chiral soliton model with a ≈ 30% rescaling of the Skyrme constant is used to estimate the mass excess of α=6 to 32 nuclides Also see calculations in (1987Sa15, 1985Po10, 1981Se06).

2015Fo04: Shell model analysis of 15Be with an emphasis on evaluating the s- and d-shell single particle energies.

Q-value: Values computed using ΔM=49821 keV 100 from 2013Sn02. This value compares with ΔM=49760 keV 400, which was estimated in 2012Wa38.
