Abstract

The long-lived radioactive nuclide ²²Na (t_1/2=2.6 yr) is an astronomical observable for understanding the physical processes of oxygen-neon novae. Yields of ²²Na in these events are sensitive to the unknown total rate of the ²¹Na(p, γ)²²Mg reaction. Using a high intensity ²¹Na beam at the TRIUMF-ISAC facility, the strengths of seven resonances in ²²Mg, of potential astrophysical importance, have been directly measured at center of mass energies from E_c.m.=200 to 1103 keV. We report the results obtained for these resonances and their respective contributions to the ²¹Na(p, γ)²²Mg rate in novae and x-ray bursts, and their impact on ²²Na production in novae.
