The hydrogen atom in momentum space

To complement the existing descriptions of amplitude functions for the hydrogen atom in terms of spatial coordinates, this review contains information about the amplitude functions in the momentum space, including several figures to illustrate the varied shapes of surfaces of these functions at constant values of amplitude. The published momentum functions display a great variety of shapes viewed in cartesian coordinates resulting from the nature of the momentum variables in the several sets.
