Extracular densities of the non-Born–Oppenheimer Hookean H2 molecule

The exact nuclear and electronic extracular non-Born–Oppenheimer density functions and their associated probability functions have been obtained for the spherical ground and excited states of the Hookean hydrogen molecule. The salient features of these complex nodal functions are discussed aided by their mean expectation values and fluctuations. The infinite nuclear mass limit is shown to appear naturally from the derived equations.
