The proton capture reactions on21Na and22Na under hydrogen burning conditions

  • Published:

Abstract

We have updated and recalculated the21Na(p, γ)22Mg and22Na(p, γ)23Mg reaction rates for temperatures 107–109 K relevant for explosive hydrogen burning in stellar environment. We find the21Na(p, γ)22Mg rate lower than recently suggested. Considering various uncertainties in spin and parity assignments of the low energy22Na+p resonances we present upper and lower limits for the22Na(p, γ)23Mg reaction rate which, however, allows for a meaningful discussion of the consequences of the new rates on the Ne - Na cycle under various stellar conditions.
