Application of electron spectroscopy for studying inverse p-decay at increasing density of neutrino flux due to diffraction

Abstract

In the present paper, a new method is substantiated for studying the inverse β-decay with the use of Auger-and photoelectron spectra for the registration of electrons, which appear at the interaction of low-energy (~ 1 MeV and smaller) electron neutrinos (ν e) with a substance. The new method is an alternative to the existing method based on the use of high-energy ν e with the energy of ~ 10 MeV, which form electrons at the interaction with a substance, the energy of which is sufficient for Cherenkov effect to appear. The offered method was realized using a high-sensitive electron magnetic spectrometer with double focusing by a non-uniform magnetic field π√2 with the cyclotron orbit radius of 100 cm, which was built at our institute; the first xray electron spectra were obtained on it and the constant of the device was determined.
