Nature of problem:
The program Compton cross sections performs the calculation of the cross-section profile for Compton scattering of gamma rays by the electrons of a complete subshell of an atom on the basis of nonrelativistic hydrogen-like one-electron wave functions.

Solution method:
Closed-form expressions for the cross-section profile are used.

Restrictions:
For energies of the scattered gamma rays near the free-electron value convergence may be too slow.

Unusual features:
Different effective atomic numbers may be used for the scattering electron in the initial bound state and the final continuum state, respectively.

Running time:
On the Univac 1108 computer less than a few minutes are required in most cases.
