Abstract

The degree to which the (p, γ) and (p,α) reactions destroy F at temperatures ∼ 1- 4 times; 10 K is important for understanding the synthesis of nuclei in nova explosions and for using the long-lived radionuclide F, a target of gamma ray astronomy, as a diagnostic of nova mechanisms. The reactions are dominated by low-lying proton resonances near the F+p threshold (E = 6.411 MeV in Ne). To gain further information about these resonances, we have used the d(F,p)F neutron transfer reaction to selectively populate corresponding mirror states in F. The results would suggest F(p,γ)Ne and F(p,α)O reaction rates that are 2-3 times lower than reported previously.
