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