Abstract

The exact expression for the width fluctuation correction factor, obtained with the Gaussian orthogonal ensemble (GOE) approach, has been implemented computationally to describe a nuclear reaction for any open channel—elastic, inelastic, capture, and fission. This exact expression is compared with various approximate expressions. It turns out that the approximate expression given by Moldauer is the closest to the GOE value. Since comparison between model predictions and experimental data alone cannot provide the answer concerning the correct approximate method, the present comparison indicates that Moldauer’s model is the one to use in reaction models for practical applications.
