Solution for Energies and Mixing of Two 0^+ States in ^10He

Using results from various reactions that populate ^10He, I conclude that the ground state has E_2n=1.07(7) MeV and the excited 0^+ state is in the region of 2.1–3.1 MeV. The amount of the (sd)^2 component in the ground state is less than about 0.075.
