Аннотация:
The spectral structure of 245-445 keV electrons and positrons in positron - throium scattering was studied. The coincident positron and electron energy spectra were measured in a double beta spectrometer. A small peak was seen in addition to Bhabha scattering at an energy about 320 keV for both the electrons and the positrons.
