The cross section for ep→epbantibX in photoproduction is measured with the H1 detector at the ep-collider HERA. The decay channel bantib→eeX' is selected by identifying the semi-electronic decays of the b-quarks. The differential cross section is measured as a function of the average transfer momentum of the beauty quarks down to the threshold. The results are compared to next-to-leading-order QCD predictions.
