N-N interaction matrix elements fromphase shifts and the jost function

Abstract

An improvement of the Born approximation based on properties of the Jost function is tested by calculating N-N potential matrix elements from experimental phase shifts. Satisfactory results are obtained with a simple plane-wave method even for the S-channel.Se prueba una mejora de la aproximación de Born basada en las propiedades de la función de Jost calculando N-N elementos de matriz potencial a partir de cambios de fase experimentales. Se obtienen resultados satisfactorios con un método de onda plana simple incluso para el canal S.
