Abstract

We have studied natural parity states in Mg26 via the Ne22(Li6, d)Mg26 reaction. Our method significantly improves the energy resolution of previous experiments and, as a result, we report the observation of a natural parity state in Mg26. Possible spin-parity assignments are suggested on the basis of published γ-ray decay experiments. The stellar rate of the Ne22(α,γ)Mg26 reaction is reduced and may give rise to an increase in the production of s-process neutrons via the Ne22(α,n)Mg25 reaction. © 2007 The American Physical Society.
