TL;DR

This paper presents an updated version of the GAMOW code that improves the calculation of broad neutron resonances using finite-range phenomenological potentials, enabling detailed analysis of the S-matrix landscape and resonance properties.

Contribution

The paper introduces a renewed GAMOW code with new finite-range neutron potentials and enhanced capabilities for locating S-matrix poles and calculating Gamow wave functions.

Findings

Successfully localized S-matrix poles in the complex plane.

Enabled calculation of normalized Gamow wave functions.

Provided detailed resonance trajectories and potential landscapes.

Abstract

A renewed version of the computer code GAMOW ~\cite{[Ve82]} is given in which the difficulties in calculating broad neutron resonances are amended. New types of phenomenological neutron potentials with strict finite range are built in. Landscape of the S-matrix can be generated on a given domain of the complex wave number plane and S-matrix poles in the domain are localized. Normalized Gamow wave functions and trajectories of given poles can be calculated optionally.
