Measurement of the spectrum of the internal bremsstrahlung from 51Cr

[摘要] The activity of the intense artificial neutrino source in the experiment BEST will be determined by measuring of the internal bremsstrahlung (IB) spectrum from51Cr. The paper describes the measurements of the IB spectrum from unsealed point-like51Cr source using spectrum recovery method, and the main sources of uncertainties are discussed.
