Abstract

Cross sections for the ²⁶Mg (p ,n)²⁶AI reaction have been measured from threshold at E_p = 4.988 MeV to E_p = 5.820 MeV. Cross sections for the ²³Na (α,n)²⁶AI reaction have been measured from threshold at E_α = 3.483 MeV to E_α = 4.597 MeV. In each case separate measurements have been to the ground state and to the first and second excited states of ²⁶AI. Cross sections for the inverse reactions have been calculated and reaction rate factors relating to the destruction of ²⁶AI in a supernova environment have been determined. Astrophysical implications relating to the observation of live and extinct ²⁶AI are discussed. Excitation functions for several additional exit channels for the ²⁶Mg + p and ²⁶Na + α reactions are reported.
