Abstract

The degree to which the (p, γ) and (p,α) reactions destroy ¹⁸F at temperatures ∼ 1- 4 times; 10⁸ K is important for understanding the synthesis of nuclei in nova explosions and for using the long-lived radionuclide ¹⁸F, a target of gamma ray astronomy, as a diagnostic of nova mechanisms. The reactions are dominated by low-lying proton resonances near the ¹⁸F+p threshold (E_x = 6.411 MeV in ¹⁹Ne). To gain further information about these resonances, we have used the d(¹⁸F,p)¹⁹F neutron transfer reaction to selectively populate corresponding mirror states in ¹⁹F. The results would suggest ¹⁸F(p,γ)¹⁹Ne and ¹⁸F(p,α)¹⁵O reaction rates that are 2-3 times lower than reported previously.
