New measurement of the Ec.m.=323 keV resonance in the F19(p,γ

Constraints on key O17(α,γ)Ne21 resonances and impact on the weak Williams1, Laird2, Choplin3 et al. 2022Phys. Rev. CSelf Cite

“…No coincidence result is reported here for the 720 keV resonance due to unknown γ -ray branching ratios and too few counts (50 observed coincidence events) to obtain a good estimate of branching ratios by fitting the BGO spectra with simulated decay schemes, as was performed in Ref. [24] for the 19 F(p, γ ) 20 Ne reaction. Our strength value is found to be in agreement with the value of 8.7 +7.0 −3.7 μeV reported by Taggart et al, though the error quoted by Taggart et al is very large.…”

The status and future of direct nuclear reaction measurements for stellar burning

“…The data taken for resonances in the 22 Ne(α, γ) 26 Mg reaction in 2019 are expected to be published in 2021. Further, the results from stable beam measurements to investigate reactions such as 22 Ne(p, γ) 23 Na [191,192], 76 Se(α, γ) [193], 34 S(p, γ) [194] and 19 F(p, γ) [195] have recently been published.…”
