A direct test of nova explosion models comes from the observation of γ rays created in the decay of radioactive isotopes produced in the nova. One such isotope, ¹⁸F, is believed to be the main source of observable γ rays at and below 511 keV. The main destruction mechanism of ¹⁸F is thought to be the ¹⁸F(p,α)15O reaction, and uncertainties in the reaction rate arise from uncertainties in the energies, spins, and parities of the nuclear levels in ¹⁹Ne above the ¹⁸F + p threshold. To measure the properties of these levels, the ¹⁹F(³He,t)¹⁹Ne*(γ) reaction was studied at Argonne National Laboratory and the Nuclear Science Laboratory at the University of Notre Dame.
