Abstract: | A cryogenically pumped gas target has been used to study resonances in the 15N(α, γ)19F reaction for Eα = 5.1 to 8.6 Mev. Gamma-ray intensity and angular distribution measurements for a resonance at Eα = 8.105 Mev, corresponding to a state at 10.411 MeV in 19F, restrict the spin and parity of the state to or . Comparison with shell model calculations indicate that the state is a strong candidate for the second (2s, 1d)3 level in 19F. |
