Variances and covariances in deconvolution of multichannel spectra: S-34 (gamma,xn) cross section

This paper discusses some aspects of deconvolution of one-dimensional spect ra in the framework of the Least Squares Method and presents a minimum vari ance regularization procedure. Covariance matrices are taken into account i n every step. Fluctuation and artifacts, both in the deconvolved and regula rized spectra, are related to the structure of the covariance matrices, The method is applied to a simulated spectrum and to the S-34 (gamma ,xn) cros s section determination from actual yield data.
