Abstract

A fairly good approximation to a neutron spectrum can be obtained commensurable with the accuracy of the activity and cross-sectional measurements. However, these approximations are valid only in regions where the coverage is determined by the cross sections and spectrum used and may be locally disturbed by poor resolution. Coverage and resolution are two properties which determine the goodness of a given monitor set. The trial spectrum influences the outcome of the unfolding only to the extent that the monitor set fails to provide the necessary coverage and resolution.
