Experimental results are presented on the pair production from high-energy photons (40–150 GeV) incident on a 0.5 mm Ge single crystal around the 〈110〉 axis. The observed enhancement increases from around 1 at threshold (40 GeV) to 7 at 1 50 GeV for photons aligned with the axis. Also the angilar dependence and the differential e+/e− spectra have been studied. For photons aligned with the axis, the results are in good agreement with calculations based on the constant field approximation.
