A recent experiment located the lowest 2+ state in 20Mg and discovered that the corresponding 2+, T = 2 state in 20F does not fit expectations of the isobaric multiplet mass equation without a d term.We have calculated the energies of the ground and 2+ states in 20Mg and the 2+ in 20F in a potential model, using shell-model spectroscopic factors. We conclude that this important 20F state has likely never been observed, and suggest a reaction to find it.
