Nature of problem:
The program calculates the form factor f(k) and the corrected form factors g(k) for the elastic scattering (i.e.Rayleigh scattering) of gamma rays by the electrons of the complete i-subshell of an atom. Each electron is described by the relativistic Dirac wave function for a one electron atom.

Solution method:
Closed-form expressions for the form factors and corrected form factors are used.

Unusual features:
To include the effects of screening the atomic number Z and the electron energy eigenvalue may be modified.

Running time:
On the UNIVAC 1108 computer, a few seconds are required.
