Multiply Scattering of Internal Conversion Electrons in Nuclear Emulsion Used on Beta-Spectrographs

The multiple scattering of β-electrons in nuclear photographic emulsion of βspectrometer is considered. A numerical calculation method was developed on the basis of many-hit model of emulsion response in frame of the theory of multiple scattering of electrons. The dependences of spectra sensitivity, of ratio signal-noise and other parameters on β-electron energy and thickness of emulsion layer were studied.
