The 14N(p,gamma)15O reaction controls the rate of the hydrogen burning CNO cycle. This reaction has recently been re-studied at E < 500keV at different facilities, including LUNA. However, also data at higher energy play a role in determining the extrapolated cross section in the R-matrix framework. Here we report on a new measurement of the absolute strength, decay branching ratio, and angular distribution of the E = 0.987 MeV (E_x = 8.284 MeV) resonance carried out at the high-current FZD Tandetron. --- This work has been supported in part by the European Union (FP6 AIM RITA 025646).
