Proton-Gamma-Winkelverteilungen an der Reaktion19F(p, α γ)16O

The angular distributions of the 6.13 MeV γ₁ transition in the reaction¹⁹F(p, α γ)¹⁶O have been measured with improved accuracy at proton energies of 873 keV and 1,374 keV using a Ge(Li) detector. The results can be fitted by Legendre polynom series witha ₂=?0,018±0.008;a ₄=0.000±0.008 atE _p =873 keV anda ₂=?0.130±0.005;a ₄=+0.004±0.004 atE _p =1,374 keV. From the measured Legendre coefficients α₁-angular momentum mixing ratios are extracted and compared with the results from (p, α₁) and (α₁, γ₁) correlations.
