Nature of problem:
In an independent particle approach, the program describes the elastic scattering of an electron from a model potential representing any atom or ion.
The program solves the radial Schrodinger equation by the log derivative method of B.R. Johnson  for a model potential to obtain scattering phase shifts and angular differential cross sections for elastic scattering. An auxiliary program computes the required input values for a parameterized Hartree-Fock, independent particle model potential of R.H. Garvey, C.H. Jackman, and A.E.S. Green .
Single channel approximation (i.e. neglect of electron exchange and coupling to inelastic channels) for elastic scattering of electrons from arbitrary ions and atoms.
Less than five seconds.
