The cross section for the reaction p+6Li→η+7Be was measured at an excess energy of 11.28 MeV above threshold by detecting the recoiling Be7 nuclei. A dedicated set of focal plane detectors was built for the magnetic spectrograph Big Karl and was used for identification and four-momentum measurement of Be7. A differential cross section of dσdΩ=[0.69±0.20(stat.)±0.20(syst.)] nb/sr for the ground state plus 1/2− was measured. The result is compared to model calculations
