Abstract

A series of astrophysical measurements was recently completed at TRIUMF, related to the unknown total rate of the ²¹Na(p, γ) ²²Mg reaction. With a high intensity ²¹Na beam from the ISAC facility, the DRAGON recoil mass spectrometer was used to directly measure seven resonances at center of mass energies from E c.m. = 200 to 1135 keV and determine their respective contributions to the ²¹Na(p, γ)²²Mg reaction rate in novae and x-ray bursts, as well as their impact on ²²Na production in novae. This study also allowed the investigation of different excited states in ²²Mg; proposed decays and spin assignments are given for the 6246, 6329, and 6609 keV levels.
