We present zero-degree differential cross sections and transverse spin-transfer coefficients DNN(0°) for the 17,18O(p→,n→)17,18F reactions at Ep=118 MeV. For the transition to the 17F(g.s.) to which several multipoles contribute, the measured DNN(0°)=−0.13±0.05 is used to separate the Fermi and Gamow-Teller contributions at 0°. The empirical Gamow-Teller strengths and the Fermi strengths are employed to estimate the solar neutrino absorption cross section in 17O and 18O.

The asymmetry A = (σ + −σ − ) (σ + +σ − ) of the reaction γ p↑↓ → π 0 p was measured at the Deutsches Elektronen Synchrotron DESY, Hamburg at a mean photon energy of 4.0 GeV in the four-momentum transfer range 0.2 (GeV/ c ) 2 ⩽ −t ⩽ 1.1 (GeV/ c ) 2 in steps of approximately 0.08 (GeV/ c ) 2 . The π 0 -meson and the proton were detected in coincidence. The asymmetry is compatible with zero in the t -range 0.2 (GeV/ c ) 2 ⩽ − t ⩽ 0.4 (GeV/ c ) 2 and negative in the t -range ⩾ 0.5 (GeV/ c ) 2 .
