Nature of problem:
A Fortran computer program for simulating Mossbauer scattering spectra for large scatterers and large detectors.

Solution method:
We calculate the intensities and energies of the allowed transitions and form the scattering spectrum as a function of the angles locating the scatterer and detector. We then numerically integrate the spectrum over the solid angles subtended by the scatterer and detector.

Restrictions:
The simulated spectra are restricted to an axially symmetric source- scatterer-detector arrangement, and the hamiltonian describing the hyperfine interactions of the Mossbauer nuclei with external fields must be diagonal in the |IM> representation.

Running time:
A typical CPU time for a 512 channel, 18-line spectrum using the IBM 360/75 computer is 2 s.
