## Description

Title of program: EXPFIT1 Catalogue Id: AANA_v1_0 Nature of problem Program EXPFIT1 solves the single channel radial Schrodinger equation in the form y''(x) = (L*(L+1)/x^2 - E + V(x)) * y(x). The test program solves the above problem for scattering of an electron by the static potential of atomic hydrogen, for a range of values of the energy E and angular momentum L. The solution is calculated to a specified accuracy; scattering phase shifts are also calculated.
