Astrophysically important 19Ne states studied with the 2H(18F, alpha+15O)n Reaction

Abstract

Facility (HRIBF) of Oak Ridge National Laboratory (ORNL) by bombarding a 720-µg/cm 2 CD 2 target with a radioactive 18 F beam. The 19 Ne states of interest near the proton threshold decay by breakup into α and 15 O particles. These decay products were detected in coincidence with position-sensitive E−∆E silicon telescopes. The α and 15 N particles from the break up of the mirror nucleus 19 F were also measured with these detectors. Particle identification, coincidence, and Q-value requirements enable us to distinguish the reaction of interest from other reactions.
