Progress Towards Low Energy Measurement of <sup>14</sup>N/<sup>15</sup>N(α, γ) Reactions

ORAL

Abstract

The St. George recoil mass separator at the University of Notre Dame was designed to study alpha capture reactions relevant for stellar burning. In one of the commissioning experiments, the measurement suffered from 18O background in the beam. A Wien filter was installed upstream of the jet gas target last year to reduce the beam contamination. The preliminary results from the recent 14N (α, γ)18F measurements, used to demonstrate 18O background reduction and the progress towards low energy measurement of 15N(α, γ)19F will be presented.
