Single-nucleon transfer reactions on ¹⁸F

Simultaneous measurement of the proton-transfer ¹⁸F(d,n) ¹⁹Ne and neutron-transfer ¹⁸F(d,p)¹⁹F reactions were performed with a ¹⁸F radioactive beam at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. The experiments clarify the nuclear structure of ¹⁹Ne near the proton threshold, which is relevant for understanding the rates of proton-induced reactions on ¹⁸F in novae. Analogs for several states in the mirror nucleus ¹⁹F have not yet been identified in ¹⁹Ne, indicating that the level structure of ¹⁹Ne in this region is incomplete. We observed 15 levels in ¹⁹Ne from the ¹⁸F(d,n) ¹⁹Ne measurement and 18 levels in 19F from the ¹⁸F(d,p)¹⁹F measurement. Angular distributions were extracted for all strongly populated states and compared to distorted-wave Born approximation calculations. The angular distributions for all the known states in the two nuclei determined in this work are consistent with their previously assigned spins and parities. The spectroscopic factors determined for these levels in the two nuclei are reported.
