First direct measurement of resonance strengths in Ne
Physical Review C—Nuclear Physics, 2011•APS
The reaction O 17 (α, γ) 21 Ne has been measured by in-beam γ spectroscopy for the first
time in the energy range E α= 750–1650 keV using highly enriched anodized Ta 2 (17 O) 5
targets. Resonances were found at E α= 1002, 1386, and 1619 keV. Their strengths and
primary γ-ray branchings are given. The new results exclude the low reaction rate of
Descouvemont and support the rate of Caughlan and Fowler. Implications for the neutron
poisoning efficiency of O 16 in the weak s-process are discussed.
