Nature of problem:
This is a revision of the Eisenstein-Miller program for calculation of collective inelastic pion-nucleus differential cross sections using free pi-N scattering amplitudes.

Reasons for new version:
This revision permits the additional use of microscopic (shell model) proton and neutron form factors. It also incorporates separate proton and neutron radii for the nuclear density rho(r) generating the distorted wave optical potential.

Running time:
CPU time of approximately 4 min was used for the test run.
