ECISVIEW. An interactive toolbox for optical model development

The software package ECISVIEW is a graphical interface built around the multi-disciplinary nuclear reaction code ECIS-95. The key feature of the working method is that the user can specify the value of optical potential parameters as any mathematical function of the energy, A, Z or user defined parameters. This enables us to obtain conveniently the optimal optical potential parameters for a given nucleus over the whole energy region of interest. ECISVIEW makes it possible to simultaneously study the dependence of all calculated angular distributions, polarizations and total cross sections on optical model parameters. This method is perhaps more than 100 times faster than the conventional method of preparing an input file, running the code, editing the output file and finally viewing the data with a graphical program. As an example, a spherical 0-200 MeV nucleon optical model for 90Zr is presented. A demonstration of ECISVIEW has been given at this Specialist's Meeting. (author)
