Photoneutron strengths in ²⁶Mg at energies of astrophysical interest

NUCLEAR REACTIONS ²⁶Mg(polarized γ, n), [circularly polarized γ beam produced in Compton backscattering of laser photons from E=498-548 MeV electrons], E=10.80-12.05 MeV; measured Eγ, Iγ, E(n), I(n), time-of-flight spectra, photoneutron σ(E) at HIγS facility of TUNL. ²⁶Mg; deduced level energies above S(n), resonance strengths, comparison with ²⁵Mg(n, γ)²⁶Mg by R-matrix analysis. Relevance to astrophysically important ²²Ne(α, n)²⁵Mg reaction.
