The Na(p,)Mg reaction in novae and x-ray bursts

The Na-21(p,gamma)Mg-22 reaction is an important link in the synthesis of Na-22 in oxygenneon novae, and serves as one of the first steps of the rp-process in x-ray bursts. This reaction has recently been studied at the TRIUMF-ISAC radioactive beam facility with the new DRAGON recoil separator. Resonant contributions have been measured for seven 22Mg states, from near the proton threshold to about 6 MeV in excitation energy. We report the results and their impact on the Na-21(p,gamma)Mg-22 reaction rate in novae and x-ray bursts.
