Abstract
The influence of a temperature of a crystal on coherent photoproduction of type B of e+e- pairs has been studied in details. In the case of detection of free pairs emitted into a given collimator size, the coherent maxima become more large and more bright following decrease of a temperature. Other temperature effect is connected with a capture of created particle to a channeled state in a crystal and can lead to a shift of position and change of the shape of coherent maxima. In the case of creation of a bound pair - positronium atom, the most sensitive to a temperature change are the angular distributions of created positronium atoms.
