Applications of Polology to Stripping Reactions

Abstract

A model-independent definition for a reduced width in nuclear reactions is proposed. In particular, stripping reactions of the form $A(d,p)B$ are studied. The applicability of polology techniques for the determination of absolute reduced widths is tested by means of a computer experiment. The results indicate that the extrapolation to the pole can give a model-independent value for the reduced width which is accurate to at least an order of magnitude. It is likely that increased accuracy is possible if such model-dependent features as the bound-state wave function are included in the extrapolation formula.
