    Abstract

    A generalized least-squares, two group neutron spectrum adjustment code is presented that uses measured reaction rates of activation foils and thermal and epithermal energy cross-section data to calculate the thermal and epithermal fluence rates in case of well-moderated neutron spectra. The code uses the covariance matrices of the measurements and cross sections to produce the covariance matrix of the calculated thermal and epithermal fluence rates. The report also gives some application examples of the code.
