Scattering amplitudes in the first Born approximation for electron-hydrogen
ic ion scattering are readily solved analytically for target's undergoing n
ear ground state transitions. However, analytic solutions involving transit
ions to higher energy states are not so easily performed. We present a comp
uter algebra solution and a Maple V Release 4 software package for analytic
ally solving the first Born approximation to the electron-hydrogenic atom s
cattering problem. Given initial and final states for the e(-)-target syste
m, symbolic solutions for scattering amplitudes, differential cross section
s and total cross sections can be calculated using this Maple package. (C)
