A program to calculate magnetic form factors for transition metal systems

Title of program: MAGFAC Catalogue Id: AABR_v1_0 Nature of problem MAGFAC calculates magnetic form factors for a transition metal ion under the influence of a crystal field. This can be defined, in the formalism of Trammell, as the expectation value of the operator representing the magnetic interaction of the neutron with the ion at a particular lattice site. The program calculates each Cartesian component of the form factor, as well as its magnitude. The spherical, dipole approximation and free atom form factors are also calculated.
