TIMEDEL: A program for the detection and parameterization of resonances using the time-delay matrix

Abstract
TIMEDEL take K-matrices from a scattering calculation, either read from a file or calculated on a dynamically adjusted grid, and calculates the time-delay matrix. This is then diagonalized to find the longest time-delay experienced by the scaterring particle. The branching ratio of decay into the open channels is also found and optionally output. A resonance shows up as a characteristic Lorentzian form in the time-delay and the program searches the time-delay for maxima. It determines, from t...

摘要
TIMEDEL程序可从散射计算中获取K矩阵（K-matrices），既可从文件读取，亦可在动态调整的计算网格上直接生成，随后计算时延矩阵（time-delay matrix）。对该矩阵进行对角化操作，以提取散射粒子所经历的最长时延。程序同时可求解粒子衰变至开放通道的分支比，并支持按需输出该结果。共振现象在时延分布中呈现为典型的洛伦兹（Lorentzian）线型，本程序会在时延数据中搜索极大值点。程序可从t...
