The probability per unit length of transformation into an electron pair of a 10/sup 12/ ev gamma quantum colliding with a thermal photon is calculated. If the energy density of thermal photons in intergalactic space is W = 0.1 ev/ cm3, the probability will be 7 x 10/sup -27/. Thus, if the distance traversed is greater than 10/sup 26/ cm the attenuation of the gamma -quantum flux may be appreciable. (auth)
