The shape and magnitude of coherent peaks are studied for the type-B coherent photoproduction of electron-positron pairs in a crystal, in the energy range of photons ω = 102-103 MeV. It is shown that under detection of pairs with restricted emission angles the coherent peaks (as a function of photon energy ω) become more brilliant, with larger value of relation of peak height to background, and lower width. The influence of channeling effect on the position of coherent maxima is estimated.
