摘要：

The O-14(alpha,p)F-17 reaction is an important trigger reaction to the alpha-p process in X-ray bursts. The most stringent experimental constraints on its astrophysical rate come from measurements of the time-inverse reaction, F-17(p,alpha)O-14. Previous studies of this inverse reaction have sufficiently characterized the high-energy dependence of the cross section but there are still significant uncertainties at lower energies. A new measurement of the F-17(p,alpha)O-14 cross section is underway at the Twin Solenoid (TwinSol) facility at the University of Notre Dame using an in-flight secondary F-17 beam. The initial results are promising but improvements are needed to complete the measurement. The initial data and plans for an improved measurement are presented in this manuscript.
