The Transformation of a Set of Multilevel Resonance Parameters into an Equivalent Set of Single-Level Pseudoparameters and a“Smooth Background”

A method is described to transform a set of multilevel resonance parameters into an equivalent set of single-level pseudoparameters and a “smooth background.”The method utilizes a Kapur-Peierls expansion of the cross sections and does not necessitate “refitting” of the data; it is illustrated by an example.
