The ¹⁸Ne(α, p)²¹Na breakout reaction in x-ray bursts: Experimental determination of spin-parities for α resonances in ²²Mg via resonant elastic scattering of ²¹Na+p

NUCLEAR REACTIONS ¹H(²¹Na, p), [²¹Na secondary beam from ²⁰Ne(d, n), E=8.2 MeV/nucleon primary reaction], E=89.4 MeV; measured E(p), I(p) σ(E) at CRIB-CNS-RIKEN facility. ²²Mg; deduced levels, resonances, J, π. R-matrix analysis. ¹⁸Ne(α, p)²¹Na; deduced α-widths, resonance strengths, reaction rates using a narrow resonance formalism. Comparison of reaction rates with previous experimental studies and statistical model calculations. Discussed impact of new rates for ¹⁸Ne(α, p)²¹Na reaction on x-ray burst (XRB) calculations.
