Some methods of neutron spectrum reconstruction on measurement results by a multispherical spectrometer

A qualitative estimation of several neutron spectra unfolding methods using data obtained with a multispheric spectrometer is presented. An algorithm is proposed using a multiparametric regularizing functional. To unfold the spectra by the algorithm mockup experiments have been conducted. The results show that if the original data are known with the accuracy of 3%, therefore the spectra unfolding errors are not more than 20-30%
