Abstract

A series of astrophysical measurements was recently completed at TRIUMF, related to the unknown total rate of the Na-21(p,gamma)Mg-22 reaction. With a high intensity Na-21 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 Na-21(p, gamma)Mg-22 reaction rate in novae and x-ray bursts, as well as their impact on Na-22 production in novae. This study also allowed the investigation of different excited states in Mg-22; proposed decays and spin assignments are given for the 62461 6329, and 6609 keV levels.
