✦ Synopsis

Generalized X-ray scattering factors have been extracted from an accurate one-electron density function of molecular hydrogen. With the approximation that the atomic densities perfectIy follow the nuclei. vibrational fore constants are given in terms of sum rules for the generalized X-ray scattering factors. Calculated (experimental) results for Hz are ke = 5.76 (5 -73) mdyne A -* , Ze = -38.7 (-36.9) mdyne A-' and me = 246 (235) mdyne A-'.
