Description

Abstract We present a detailed description of a FORTRAN code for evaluation of the resonance contribution a Regge trajectory makes to the integral state-to-state cross section (ICS) within a specified range of energies. The contribution is evaluated with the help of the Mulholland formula (Macek et al., 2004) and its variants (Sokolovski et al., 2007; Sokolovski and Akhmatskaya, 2011). Regge pole positions and residues are obtained by analytically continuing S-matrix element, evaluated numerically for... Title of program: ICS Regge Catalogue Id: AEST_v1_0 Nature of problem The package extracts the positions and residues of resonance poles from numerical scattering data supplied by the user. This information is then used for the analysis of resonance structures observed in elastic, inelastic and reactive integral cross sections. Versions of this program held in the CPC repository in Mendeley Data AEST_v1_0; ICS Regge; 10.1016/j.cpc.2014.03.030 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
