A discussion is presented of the influence of photon multiplicity in the emission from channeled electrons on the radiation spectrum measured by a total-absorption spectrometric device. It is shown that as the maximum in the spectrum shifts with increasing crystal thickness, in the absence of further information it is impossible to determine the multiplicity of the emission. A method is proposed for determining the presence of multiple emission from channeled electrons with a total-absorption spectrometer by using an absorber covering a specified portion of the γ-ray aperture. The presence of multiplicity is identified in emission from channeled electrons with energy E0=900 MeV in a tungsten single crystal of 1.18 mm. Previously the presence of multiplicity in the radiation from channeled electrons had been detected for electron energies above 4.5 GeV.
