Description
One of the main contributions to the production of 19F is the 15N(α, γ)19F re-
action, which occurs during the Helium burning phase in different astrophysical
sites including AGB stars and Wolf Rayet stars. However the reaction rate at
astrophysical energies is still poorly known.
Here we report on a measurement of different resonances of the 15N(α, γ)19F re-
action in the 0.5 - 1.5 MeV center-of-mass energy range, performed at the 5 MV
Felsenkeller shallow-underground accelerator in Dresden, using tantalum nitride
solid targets enriched in 15N, multiple HPGe-detectors and the new FeliciTAS
