Resfit — A multichannel resonance fitting program

Title of program: RESFIT Catalogue Id: AAFX_v1_0 Nature of problem This program fits K-matrices for cases, where a single discrete autoionising state interacts with several continua, to the form given by Burke. The background K-matrix and its first and second derivatives are calculated together with the position and the partial and total widths of the resonance. Versions of this program held in the CPC repository in Mendeley Data AAFX_v1_0; RESFIT; 10.1016/0010-4655(86)90022-6 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)程序名称：RESFIT 目录编号：AAFX_v1_0 问题概述 本程序适用于单个离散自电离态与多个连续态相互作用的场景，可将K矩阵（K-matrix）拟合为伯克（Burke）提出的形式。同时可计算背景K矩阵及其一阶、二阶导数，以及共振的位置、分宽度与总宽度。 存放于Mendeley数据平台的CPC（Computer Physics Communications，《计算机物理学报》）程序库中的该程序版本： AAFX_v1_0; RESFIT; 10.1016/0010-4655(86)90022-6 本程序源自贝尔法斯特女王大学馆藏的CPC程序库（1969-2019）
