Abstract

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. © 2011 American Physical Society.
