摘要：

The characteristics of a beta spectrometer that consists of a total-absorption Si(Li) detector and a drift Si detector are presented. Using this spectrometer, it is possible to efficiently separate beta radiation of nuclei from concomitant X and gamma rays. The method is based on coincidences between signals from the thick and thin detectors. The spectrometer can be used to precisely measure the shape of the beta spectra of various radioactive nuclei, in particular, of the Pr-144 nucleus, which is the most promising antineutrino source for searching for neutrino oscillations into a sterile state.
