A computer code for simulation of electron-hydrogen scattering. Contains four sub-programs: (a) “hex-ecs” which solves the Schrödinger equation in the B-spline basis, (b) “hex-dwba” which computes scattering variables for high energies using the distorted wave Born approximation of the first order and finally (d) “hex-db” which is a user interface to a plain SQLite database, where the intermediate results are being stored, and which is used to extract derived quantities like a cross section from it.
