Mixing of 2+ states in 20Ne☆

Abstract The broad 8.8 MeV 2 + state of 20 Ne is seen to be populated with appreciable strength [(2 J + 1) S = 0.21] in the reaction 19 F(τ, d) 20 Ne, even though this strength would be zero in the simplest model. A model previously used to explain the mixing of 0 + states is found to work surprisingly well for the 2 + states.
