About "debye"--Lattice dynamics and heat capacity

"debye" calculates a variety of quantities related to the phonon spectrum and specific heat of fcc crystals with nearest neighbor interactions. It calculates from the Debye model, as well as from the lattice dynamic model, and compares the results with experimental heat capacity data for aluminum, copper, and lead. Neutron scattering data may also be displayed for comparison with the model dispersion relations, for all three metals.

"debye" was programmed by Joerg Draeger, and derived in part from a problem developed by Doug Fitchen.
